✦ Synopsis

This article describes an error measurement and mesh optimization method for finite elements in non-linear geometry problems. The error calculation is adapted from a method developed by Ladeveze, based on constructing a local statically admissible stress field. The particular difficulty in non-linear geometry lies in choosing a configuration on which the fields is defined. We propose here the lagrangian or reference configuration. The error is then defined as the value in elastic energy of the difference between the two stresses. The optimization used is the type h version.

An rh-method, which combines r-and h-methods, is proposed for cost-eective adaptive FE analysis in twodimensional linear elastic problems. Through various numerical test examples, the rh-method is compared with the h-method. From these examples it is concluded that the rh-method has the advantages o
