SolidMechanicsStress
SolidMechanicsStress[vars,pars,strain]
yields solid mechanics stress with variables vars, parameters pars and strain strain.
SolidMechanicsStress[vars,pars,strain,displacement]
yields solid mechanics stress for nonlinear material laws.

- SolidMechanicsStress returns the mechanical stress from a given strain with dependent variables of displacement
,
and
in units of
, independent variables
in
and time variable
in units of
.
- Stress is a resistance force per cross-sectional area
.
- Stresses have the unit of
.
- SolidMechanicsStress uses the same variables vars specification as SolidMechanicsPDEComponent.
- SolidMechanicsStress uses the same parameter pars specification as SolidMechanicsPDEComponent.
- A SymmetrizedArray specifies strain.
- Typically, strain is the result of SolidMechanicsStrain.
- For elastic materials, SolidMechanicsStress uses the elastic strain to compute the stress.
- SolidMechanicsStress removes thermal or initial strains from the given strain.
- SolidMechanicsStress returns a SymmetrizedArray of stresses of the form:
- The
represent the normal stress and
represent the shear stresses.
- For nonlinear materials, SolidMechanicsStress uses the strain and displacement to compute the stress.
