How you'll learn
Delivered 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Ansys nCode DesignLife, Abaqus, LS-DYNA, Minitab and COMSOL Multiphysics, in free, academic or evaluation versions. Practical work is based on real procedures: cyclic corrosion tests in a climatic chamber, mechanical characterisation of welded and bonded joints, and failure analysis of joints on field vehicles. Assessment is continuous by module, plus the final capstone project.
Standards covered: ISO 9227, ISO 12944, VDI 2230, ISO 9223, VDA 233-102, ISO 4628, ISO 14273, ISO 4587.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
