Finite Element Analysis of Adhesive Bonded Joints

In this article, I’ll briefly discuss a simple analysis procedure to evaluate bonded structures using FEA. This procedure can be extended to the finite element analysis of more complex structures involving bonded joints. Adhesive bonded joints are an excellent alternative to mechanical fasteners and in some cases it might be the only solution. Adhesive joints […]

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 […]
