Decided by: Education Board D
Date of Decision: 2013-04-19

General Information

Elective for: F4, F4-bem, M4, Pi4, Pi4-bs, V4-ko
Language of instruction: The course will be given in English on demand

Aim

The course has two aims. On a general level, the aim is to provide knowledge about strategies for high-performance computing. This is to a large extent achieved through working with structural dynamics applications. Thus, the other aim is to give solid knowledge about methods within modern structural dynamics and application of those within various fields of structural design, i.e. building and vehicle design.

Contents

Single-dof models. Generalized Single-dof models. Time integration; Newmark’s method, implicit method, explicit method. Multi-dof models; finite elements, direct integration, modal superposition, eigenvalue analysis, response diagram. Earthquake analysis.

The lectures describe the theoretical concepts in relation to the application, with conceptual construction assignments which show how the realistic questions enhance the mathematical and numerical descriptions. The construction assignments relate to applied mechanics with the finite element method as basis for the work.

Beyond this moments dealing with general computer code systems for finite element analysis, i.e. Abaqus, Nastran or LS-Dyna are planned. This kind of computer code systems can be used in a wide range of physical/engineering problems. Construction assignment 2 is designed so that it is natural to use one of these systems. Further, computer systems and computational strategies for high performance computing are discussed. The computer systems that Lunarc have at their disposal will also be used in the course.
