# Axial stress, strain and extension
# Scope: Uniaxial linear elastic material response.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

stress = 100 MPa
modulus = 200 GPa
length = 100 mm

strain := stress/modulus
extension := strain*length [mm]

check elastic strain screen: strain <= 0.001

scenario alternative: stress = 80 MPa
