METHOD FOR DETERMINING CONSTRAINTS, DEFORMATIONS, DAMAGE TO PARTS CONSISTING OF SOLID MATERIAL

摘要

P Method for determining the effects of a mechanical stress on an object made of a material in which the deformations and stresses generated by the mechanical stress at a plurality of points of the object are calculated by means of a method numerical calculation in anelastic mode in which the behavior of the material is represented by a polycrystalline microscopic behavior model using at most ten "grain" bricks, the deformations of which are determined from at most six sliding systems, and possibly at most seven "grain boundary" bricks, whose deformations are determined from at least one system and at most one "hole" brick having a variable volume fraction, the plastic deformations of which are purely voluminal. / P
