1. Analytical methods versus numerical methods ? advantages, disadvantages, basis definitions of matrix calculus and calculus of variation. 2. Energy principals (Lagrange, Castiglian), Ritz?s variation method. 3. Principal of FEM, duality (deformation variant, force variant), element stiffness matrix. 4. The overall stiffness matrix, load (mechanical, thermal), boundary conditions, system of linear equations and its solution. 5. Finite elements and their usage ? beam elements. 6. Finite elements and their usage ? plane elements, shell elements. 7. Finite elements and their usage ? solid elements, special elements (MASS, GAP, STRING, axially-symmetric element). 8. Linear statics, displacements, strains, stresses. 9. Result evaluation of linear statics, stress categories, strength, fatigue. 10. Presentation of some real technical problems, usage of various types of elements.

Learning outcomes
|
The aim of this subject is to introduce students into the finite element method (FEM) applied to problems of linear statics and natural vibration of structures. The students will learn a theoretical bases of the method and to solve individually practical tasks by means of the computer program Solidworks Simulation, as well.
Graduating the subject, the student can solve individually simpler tasks of linear statics. Based on the achieved results of the analysis, the student is able to evaluate strength and fatigue according to valid norms and standards or according to modern scientific and technical knowledge, respectively.
