摘要：

In order to ensure the reliable dimensioning of micro components the influence of the material anisotropy of grains upon the local stress under load is investigated. Based on a point process a program for the generation of micro components with their three-dimensional microstructure for the finite element analysis has been developed, in order to determine the strains in micro components which have only few grains in critical areas. The limitation of the finite element analysis with isotropic material models and the necessary consideration of the microstructure have been investigated in detail. Now it is possible to provide designers with additional knowledge to design efficient and reliable micro components.
