A SURPRISINGLY simple FEA method to determine BULK MODULUS

This video shows a surprisingly simple finite element based approach of determining the Bulk Modulus of a homogeneous block of Polypropylene. Here, the theory behind numerical model setup was explained, the model set and ran, and bulk modulus determined. To prove it works, I determined analytically the bulk modulus and this was found to agree with the numerically determined bulk modulus. This approach will be useful for analysis of bulk modulus of heterogeneous media like lattice and syntactic foam structures.
