Procedure for the determination of forces, deformations and damage of parts made of a solid material.

摘要

Procedure for determining the effects of a mechanical force on an object consisting of a solid material whereby the deformations and the forces generated by the mechanical stress in a series of object points by a method of numerical calculation in anelastic mode are calculated in which the behavior of the solid material is represented by a model of polycrystalline microscopic behavior using a series of blocks "grain" whose deformations are determined from a series of individual systems of sliding of solid material, the trace of the tensor zero microscopic deformations, each block "grain" orientation and volume fraction, characterized in that: - the number of blocks "grains" is less than or equal to ten, - the number of sliding systems is less than or equal to six, moreover, the microscopic model uses: - up to seven blocks "grain boundary" each l I which has an orientation and a volume fraction, whose deformations are determined from at least one opening system, being positive the trace of the tensor of the microscopic plastic deformations of each block "grain boundary", - at most one "hole" block having a variable volume fraction, whose plastic deformations are purely volume and whose trace of the tensor of the microscopic plastic deformations is positive.
