A Material Model with Softening Effect Considered

Abstract:

Precise analysis on large-span spatial structures depends on accurate numerical material constitutive model, According to the axial tension stress-strain curve, the paper proposes a new numerical multiline material model, with material effects of intenerating effect, material hardening effect and damage effects considered, and corresponding calculation method applicable to beam element. Simulation of axial tension test and bi-level loading test on cantilever column proves that the material model and algorithm are effective and correct.
