Increasing element temperature as strain increases? Used to incorporate Soil shear modulus reduction

Increasing element temperature as strain increases? Used to incorporate Soil shear modulus reduction

Increasing element temperature as strain increases? Used to incorporate Soil shear modulus reduction

(OP)
Hi everyone,

I am trying to incorporate the Shear modulus reduction curve. This is basically a curve that shows the relationship of the modulus with changing strain (modulus of soil decreases as strain increases).
First of all, is there a way to incorporate this without defining a umat? And if the only way is umat, where can I learn how to write a umat code?
I know there is a way to change the properties of elements for different temperatures, so I was thinking of checking there is a way to automatically make elements get hotter(increase temperature) as their strain increases? And then for each value of strain they will have different properties?

I am simulating soil-pile interaction of a pile embedded in soil (dry sand with 100% relative density) under dynamic loading (earthquake). During the time-history of the earthquake certain elements face high strain therefore, their properties (shear modulus) should decreased based on their strain.

Thanks in advance.
