uniaxialMaterial

Several uniaxial materials are available for DDM-based FE response sensitivity computation.

SteelMP Material

This command is used to construct a uniaxial Menegotto-Pinto steel material object.

SmoothPSConcrete Material

This command is used to construct a uniaxial smoothed Popovics-Saenz concrete material object.

UniaxialJ2Plasticity Material

This command is used to construct a uniaxial J2 Plasticity material object with isotropic and kinematic hardening.

Hardening Material for Sensitivity

This command is used to construct a uniaxial material object with combined linear kinematic and isotropic hardening.

Concrete01 Material

This command is used to construct a uniaxial Kent-Scott-Park concrete material object with degraded linear unloading/reloading stiffness according to the work of Karsan-Jirsa and no tensile strength (refer to http://peer.berkeley.edu).

Steel01 Material for Sensitivity

This command is used to construct a uniaxial bilinear steel material object with kinematic hardening and optional isotropic hardening described by a non-linear evolution equation (refer to http://peer.berkeley.edu).

Elastic Material

This command is used to construct a linear elastic uniaxial material object (with optional material damping).
