Stress-strain data is fundamental to the analysis of structures since important decisions related to failure and integrity of structures are based on this data and on material properties derived from this data. Therefore, it is very important that engineers have a good grasp of engineering material properties as well as how to convert test data from a mechanical testing device into stress strain curves useful for design and analysis

Finite Element Models of Varying Fidelity
Models of various fidelity can be used for analyzing structures or any physical system. The decision is made based on desired results as well as computational resources available. In this blog, I’ll compare finite element models of varying fidelity using ANSYS finite element analysis software. The example used for comparison is a simple tubular, cantilever […]

Validating FEA Results
The purpose of this article is to post-process and understand FEA results by comparing with standard text book theory and hand calculations. I will use the example of a cantilever I-beam loaded by a point force at the end. Simple hand calculations based on fundamental equations of solid mechanics is the best way to validate finite […]
