The content of the final assignment is based on the Digital Image Correlation (DIC), with which we compare the displacement and deformation fields in loaded products. The digitally acquired data, we then use to determine the loads in the product, which can be used to predict the products lifespan and load capacity.
Due to the variety of materials, in most cases the rheological relationships and material parameters are unknown, so we cannot determine the stress field.
If we can assume the isotropic nature of the material and the consequent co-linearity of strains and stresses, we can determine the stress field using the finite difference method.
