AUTOMATIZATION OF STRESS ANALYSIS

FAST-5D0Acad. year: 2020/2021

Presentation of basic software products used for analysis of beam structures, possible utilization and advantages of their application. Developing of analysis models and their optimalization with respect to their real constructional and technological design. Individual structure entities (nodes, hinges, beams, rigid arms, etc.). Modeling of entities with focus on the beam structure. Simplifying prerequisites and their implementation to the Finite Element Method within the analysis models. Classification of the load type (permanent, variable), entering the load cases and the combination variants of the load cases specification in the individual software products. Basic information on the geometrically nonlinear problems and their comparison to the linear stability. Basic information on the dynamics of structures. Real application of the software products for the structure design.
