Department of Mechanics, Biomechanics and Mechatronics

Synopsis:

In the course will students introduced with numerical program ABAQUS. In the course will be solved typical tasks, which are common in technical practice and especially tasks focused on the biomechanics applications by means of Finite Element Method (FEM). Each lesson will be devote to practical using of the solver program possibility for stress and strain analyses creating of the 2D and 3D parts, choice of the optimal element type, possibility of material properties modeling (elastic, hyperelastic. anisotropy, composite, etc.), static solution linear/nonlinear, contact, choice and possibility of the boundary conditions, thermal loading, dynamic loading. Students will separately create numerical analyses partial exercise accordance with instruction presented on the web pages. Each student must analyze a simple task and give in a report.

Requirements:

Study Objective:

Aim of the course Finite Element Method used in Biomechanics is show due the practice using of the program ABAQUS in practice tasks. In the course will be solved typical tasks, which are common in technical practice and especially works focused on the biomechanics applications. Main aim of the course is practical demonstration of the method of simulations, evaluation and visualization of FE analyses results.
