Example 7.7 Linear visco-elasticity of orthotropic laminated composite with Abaqus UMAT

In Example 7.7, to simulate linear visco-elasticity of orthotropic materials, we program the constitutive equations into a UMAT, available on my Website. See example 7.4 in the textbook to learn how to calculate, using MATLAB, the visco-elastic properties of the lamina in terms of the properties of the fiber and matrix. In this example, we use the visco-elastic properties of the lamina to simulate a visco-elastic laminate [0/90_8]s. Additional details in the textbook "Finite Element Analysis of Composite Materials Using Abaqus" Multilingual CC available.

Thank you Sir for the Video. Can you please tell how can I extend this code for Generalized Maxwell model?

[gaganaut]

Hi, how can we include time temperature superposition also into the model
