Title: | Influence of thermal boundary conditions on the parameter identification in thermodynamics |
Language (ISO): | en |
Abstract: | Finite-Element based identification schemes, such as the FEMU-method, are a powerful tool for the (quantitative) adjustment of material models to an observed material behaviour. A relative sparingly explored segment of this field, however, is the identification of thermal material parameters based on full field temperature measurements. Hence, the focus of this contribution lies on the influence of thermal boundary conditions on the result of such an identification. More precisely, the impact of the convection and conduction coefficient is analysed by simply performing several identifications, each with different values prescribed. Results suggest that some parameters are indeed very sensitive to the choice of coefficients. |
