This Course is useful for all engineers who wish to make their basics clear in Pipe stress analysis. If you wish to "Experience" the "Stress Concept" and not only wish to understand it mathematically or in bookish language and the most importantly if you possess patience and passion for the subject then this Course is for you. This Course is divided in 3 nos. of videos. In these Courses we will discuss
The concepts of Displacement Filed, Stress & Strain Field,
Modulus of Elasticity and its significances
what is 'Tensor'? stress as a Tensor
Longitudinal stress, Radial stress, circumferential (Hoop) stress
Moment of Inertia
stress stain curve and practical approach to look towards it.

This Course is continuation of Course-1 and hence applicable for all Mechanical, production engineers irrespective of their experience. This Course is extremely recommended for the under graduates, fresh graduates, piping engineers, engineers working at site and stress engineers. We go little deeper into concepts like
3D state of stress
Mohr's circle
Theories of Failures
Maximum Shear Stress Theory
Von mises theory
Importance of stress analysis
Also, a simple problem is solved by hand calculations to calculate the stresses in the system. The intention of this Course is to make the participant to look at the problem without taking help of software

A highly recommended Course for all stress and piping engineers. There are various codes based on their applications. For example, ASME B31.1 is for Power piping, B31.3 is for Process Piping, B31.4 is for Liquid Hydrocarbon transportation etc. It is like "learning languages very close to each other". If you know one language and its grammar well then it is simple to grasp other languages. Unfortunately, most of the Piping engineers do not read the code carefully, some of them "Read" the code but cannot "interpret" it. The equations provided in the codes are followed as it is. However, all these equations are closely related to basic stress concepts and engineering theories which we learn in schools, universities and if an engineer understands "Why" behind the code equations, are written in a particular way then he/she gets an ability to relate them with new challenging problems. Also, it makes the understanding of code clear.
Primary stresses and their characteristics
Secondary stresses and their characteristics
Occasional stresses and their characteristics
Which type of stress is more critical
Mode of failure of each type

This Course is continuation of previous Course and hence must be heard after completing Course 3. This talks about the code equations in detail
why equations are written in a particular way
what is the significance of + and - sign?
what is 'stress range'?
stress relaxation
Self-springing of material
what are liberal stresses
Scope and Exclusions of ASME B31.3
Primary stresses equation and its allowable
secondary stresses equation and its allowable
occasional stress equation and its allowable

Defining the load cases is very important in pipe stress analysis as it is a relation between the software and the code requirements. Defining right load cases and understanding the mathematics behind the load cases is very essential. Most of the time it has been observed that engineers do copy the load cases or try to learn them by heart.
how to write load cases their nomenclature
there are various methods of combination such as scalar algebraic.
Also, it tells about the answers of many critical questions like 'why a particular load case is written in a particular way'?
how to write the load cases using Caesar II software
What are the different types of load cases?
How the allowable stresses are understood by the software when you call a particular load case by a particular name
How to write the load cases when a spring is introduced in the system.
How to write load cases when force present in the system.
This model also relates the load cases with the code equations. This Course is extremely useful to the engineers with experience less than 5 years for those who wish to understand the mathematics and 'Why' behind the load cases.

Today's world is software driven. Engineers are no exception to it. It has been observed that engineers cannot give the solution without having software with them. Then it becomes essential to know the advantages and the limitations of the tool we are using. Hence knowing the stress analysis software and its advantages / limitations, the way it has been programmed etc. is very important. CAESAR II is one of the finest stress analysis software using beam element.
basic elements true
hand calculation of thermal force and stresses. Evaluating them with scissor to answer
how software works
important features of configuration setup
what is 'degree of freedom'
introduction to modelling commands
Node and connecting Node, its application
how to apply wind and earthquake loads
advantages and limitations of the software
difference in pipe element and rigid element

Course number 7 is continuation of Course number 5. In Course number 5 we had learnt the theory about the load cases, how to write them, and its combination methods. In this Course we are going to learn how to build the load cases in CAESAR II software.
What are the different features of this wizard?
How to make the most out of the various advantages provided by the software
How to apply wind, earthquake, forces in the load cases
How to interpret the results.
How to correlate the results with the code
How to identify whether liberal stress is on or not
How to interpret the positive and negative sign convention in CAESAR II
How to backtrack the sources of forces and stresses by integrating the results

After completing Course number 1 to 7 successfully, we have reached a stage where we should start doing experiments. For a stress engineer it is essential to keep trying, doing experiments, making changes to the model, and observing the results. At the initial stage, this 'trial and error' method is very effective to learn stress analysis. Engineers should start predicting the results of small models and verify them with CAESAR II software. The answers we get teach us a lot. This Course is designed keeping in mind that the listener is new to the software.
study the effects of temperature, supports and layout on the results
how to reduce the forces and moments
basic techniques how to solve a stress system, comparing the results
Learn few handy commands like Copy, duplicate and rotate
liberal stress and its effect on allowable stress

Our trainer strongly believes that when any stress analysis problem comes in front, the solution of that problem should first form in your mind. Then one should model it accurately in the software and look at the results. If the results match your predictions, you are on the right track; if not, you can correct your understanding by examining the software output. This course covers how previous generations performed analysis without sophisticated software. We will learn how to calculate SPAN of a pipe based on 'allowable stress', 'allowable deflection', and natural frequency. Further, we will study the 'Guided Cantilever Method', solve a problem using hand calculations, and verify it using CAESAR II software to compare accuracy and limitations.

The final outcome of extensive stress analysis is the 'IFC isometric' (Issued for Construction). These isometrics give the final pipe route and type of supports approved by the stress engineer. Understanding the different types of supports and converting software recommendations into physical supports is essential. This course covers:
Different types of supports and their applications
Where to use which type of support
Do's and don'ts about supports
How to read arrow markings on stress isometrics and convert them into physical supports
Simple and some complicated supports
Primary and secondary supports
This course is useful for piping engineers, designers, stress engineers, mechanical contractors at site, and civil engineers.
