Problem description

Material:

Elasticity

Young's modulus, E = 4.65E6

Poisson's ratio, ν = 0.18

Plasticity

Biaxial/uniaxial compression stress ratio = 1.18

Uniaxial tension/compression stress ratio = 0.1

Biaxial/uniaxial compression plastic strain ratio = 1.25

Tensile cracking stress/compression stress ratio = 0.2

Hardening curve:

Cracking tensile stress decreases linearly to reach zero at strain = 5.0E−4.

For constant fracture energy cracking cases (mcou0o[1/2/3]hut.inp) cracking tensile stress decreases linearly to reach zero at displacement = 6.0E−4.

(The units are not important.)
