Here, we demonstrate the performance of the enhanced assumed strain element Q1E4 using beam clamped on one end and subjected to a load on the free end. This problem is commonly referred as Cook's membrane. The material is taken as a nearly incompressible.

Firstly, we consider linear elasticity with $E = 250$ and $\nu = 0.4999$

!!!!!!!!!!!!!!!!!!!!!!!!!!!!Results are coming soon!!!!!!!!!!!!!!!!!!!!!!!!!!

Secondly, we use large strain model

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Under construction!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
