Non Linear Residual Stresses(Y lies between 0&η)
Non Linear Residual Stresses(Y lies between 0&η) is stress fields that exist in the absence of any external loads and are the result of any mechanical process which can cause deformation.
Symbol: σnon_linear
Measurement: StressUnit: MPa
Note: Value can be positive or negative.
Yield stress(non-linear)
The yield stress(non-linear) is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically.
Symbol: σy
Measurement: StressUnit: MPa
Note: Value can be positive or negative.
Depth Yielded Between 0 and η
Depth Yielded Between 0 and η is the amount of material deformed between the surface and a specified depth η, indicating residual stresses.
Symbol: yd
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Depth of Outermost Shell Yields
Depth of Outermost Shell Yields is the distance from the surface of a material to the outermost shell where residual stresses are present.
Symbol: η
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Material Constant
Material Constant is a measure of the internal stresses that remain within a material after the original cause of the stress has been removed.
Symbol: n
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Recovery Stress in beams for non linear relation
Recovery Stress in beams for non linear relation can be defined as when a beam so bent is applied with a moment of same magnitude in the opposite direction, then the recovery of stress takes place.
Symbol: σrc
Measurement: StressUnit: MPa
Note: Value can be positive or negative.
