Target audience: Design, Simulation, Analysis, Research and Development.

Date: Wednesday-Friday June 7-9, 2017
Place: Weld on Sweden, Videum Science Park, SE-351 96 Växjö
Lecturer: Professor Zuheir Barsoum

The finite element analysis is nowadays a widely used tool and new developed design codes are applicable with better accuracy and precision.

In this course, methods for fatigue analysis of welded structures using FEM and fracture mechanics are taught.

Computer exercises are scheduled and assistance with the exercises is provided during the course.
