TY - CONF A1 - Wu, Cheng-Chieh A1 - Weisbrich, S. A1 - Neitzel, F. T1 - Approximate model for geometrical complex structures N2 - Many engineering structures are made of composite materials or metal foam. To simulate the deformational behaviour of these structures often requires a high number of discretisation elements. This in turn yields a very large system of linear equations that are extremely time and memory consuming or practically impossible to solve. It is therefore desirable to find an approach to overcome this obstacle.

A1 - Neitzel, F. T1 - Inverse finite element adjustment of material parameters from integrated analysis of displacement field measurement N2 - The integration of finite element method (FEM) into the least-squares adjustment presented in is further extended for a joint evaluation of an elastostatic model and displacement field measurement. For linear solids which obey the Hooke's law, the material parameters determination from measurements is being examined.
