FINITE ELEMENTS METHOD IN MECHANICAL DESIGN
Learning outcomes of the course unit
The course introduces the basic concepts of an computational method of
analysis increasingly used in mechanical design. The aim is to have
the student apply the method to practical cases and appreciate its
potential and limitations
