Research questionHow can we infer path-dependent material stress responses from strain histories when internal states are unmeasurable?Plasticity and damage depend on latent material states that experiments cannot directly measure, so stress depends on loading history rather than current strain alone. The challenge is to recover irreversible stress responses from measured strain–stress data without explicitly specifying those hidden states.
