Elastic-Plastic
Fracture Mechanics
Elastic-plastic
fracture mechanics (EPFM) can be used when the amount of cracktip
plasticity that precedes or the fracture event is much larger
than that permissible in LEFM. If the crack tip plasticity
is sufficiently large, it may be reflected in nonlinear overall,
load-deflection behavior of the structure. Examples of materials
which lend themselves to EPFM analyses include austenitic
stainless steels and ferritic steels at high temperatures.
The pc-CRACK
EPFM module includes nine (9) models from the EPRI EPFM Handbook
to characterize cracking for ductile and semi-ductile materials.
This module also performs instability analyses based on the
J-Integral/Tearing modulus approach.
