The Accumulated Equivalent Plastic Strain result is the summation of the Equivalent Plastic Strain result increment for each step. Equivalent Plastic Strain is calculated from plastic strain components directly and Accumulated Equivalent Plastic Strain is integrated from the equivalent incremental plastic strain along the deformation path. This result is an indicator for the hardening of an engineering body. Accumulated Equivalent Plastic Strain is based on the alternating loading and the values are always increasing (like plastic work).

Accumulated Equivalent Plastic Strain and Equivalent Plastic Strain are equal for proportional, monotonic loading, only.

Large Deflection Effects

Note that the display of this result changes based on the setting of the Large Deflection property. When the property is set to On, the result displays zero values for any body with non-linear materials, as illustrated for the three body part shown below.

Setting the property to Off, the same body with non-linear materials displays transparently. This display is like the Equivalent Plastic Strain result that displays non-linear materials transparently regardless of the Large Deflection property setting.
