How you'll learn
100% online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetable: students progress at their own pace within the intake, which makes it possible to combine the course with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is ANSYS Mechanical, Femap with Simcenter Nastran, DNV Sesam, nCode DesignLife, in free, academic or evaluation versions. Exercises are based on real assessment procedures for hot spot evaluation of welded details by finite elements, cumulative damage calculation with a wave spectrum, and crack inspection by non-destructive testing. Assessment is continuous per module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
