Abstract

The present disclosure relates to an information processing device, an information processing method, and a program for enabling more accurate prediction of a crack to be made. A model acquisition unit acquires a structure model MD from a model generation unit, an external device (not illustrated), or the like. Amplitude load energy A in an element E0 having no cracks is set on the basis of a relationship between an equivalent stress σ and an equivalent elastic strain ε experimentally obtained according to a material constituting the element E0. Since the equivalent elastic strain ε depends on a crack variable φ, the amplitude load energy A is expressed as a function of the crack variable φ. A crack prediction unit predicts a crack to be generated in a structure D by calculating a differential equation having a term proportional to the amplitude energy. The present disclosure can be applied to, for example, a crack prediction device that predicts a crack.
