I have quesstion in abaqus.I want to have elastic and plastic part in material curve.I need help to have ultimate stress in stress strain curve in material propertiy and after that my material fail.
please help me.
Dear all,
I am using Abaqus to model concrete as an elastic material. However, the failure criteria available in the software is only for 2D elements and are dominated by a maximum normal stress (fail stress option) or normal strain (fail strain option) value.
I was wondering if anyone would know how to model concrete as an elastic material following "theory of elasticity" and failing by a maximum TENSILE strain value in any of the three directions given a material's point.
It would also be perfect if deleting elemnts option can be used in this case.
Review of Elasticity Equations
Linear, homogeneous, isotropic material behavior.
Silicon can host a large amount of lithium, making it a promising electrode for high-capacity lithium-ion batteries. Recent experiments indicate that silicon experiences large plastic deformation upon Li absorption, which can significantly decrease the stresses induced by lithiation and thus mitigate fracture failure of electrodes. These issues become especially relevant in nanostructured electrodes with confined geometries.
