content:

Repetition of fundamentals of strength of materials and introduction into continuum mechanics of solids: stress and strain tensors, balance equations, constitutive equations of linear elasticity,
formulation as boundary value problem and variational problem (principle of virtual work) introduction into the finite element method (FEM): discretization of the continuum, shape and displacement functions, isoparametric elements, (elastic) constitutive equations, local and global stiffness matrices and load vectors, solution of equations, general structure of a FE programme: input data, flow diagram of problem solution, results,
application of the FE programme ANSYS with computer exercises: meshes and other input data, FE simulations, presentation, evaluation and interpre-tation of results, individual working on case and parameter studies: bending of a rectangular panel, panel with hole under biaxial tension, smooth and notched tensile bars, cylindrical pressure vessel etc.
