Elastic material model - el_mat

This is a simplified uniaxial elastic material model with symmetric behaviour in tension and compression.

Two model calibrating parameters must be defined in order to fully describe the mechanical characteristics of the material:

Modulus of elasticity - Es
This is the initial elastic stiffness of the material. The default value is 200 GPa.

Specific weight -
This is the specific weight of the material. The default value is 20 kN/m3.
