StructAnalysis

A set of extended mechanical properties related to steel (or other metallic and isotropic) materials.

Inputs

NameIDDescriptionType
YieldStressYA measure of the yield stress (or characteristic 0.2 percent proof stress) of the material.Number
UltimateStressUA measure of the ultimate stress of the material.Number
UltimateStrainSA measure of the (engineering) strain at the state of ultimate stress of the material.Number
HardeningModuleHA measure of the hardening module of the material (slope of stress versus strain curve after yield range).Number
ProportionalStressPA measure of the proportional stress of the material. It describes the stress before the first plastic deformation occurs and is commonly measured at a deformation of 0.01%.Number
PlasticStrainSA measure of the permanent displacement, as in slip or twinning, which remains after the stress has been removed. Currently applied to a strain of 0.2% proportional stress of the material.Number
RelaxationsRMeasures of decrease in stress over long time intervals resulting from plastic flow. Different relaxation values for different initial stress levels for a material may be given. It describes the time dependent relative relaxation value for a given initial stress level at constant strain. Relating values are the 'RelaxationValue'. Related values are the 'InitialStress'Number
