Great class! I truly hope that there are further materials on shell elements, non-linear analysis (geometric nonlinearity, plasticity and hyperelasticity).

Well worth the time if you wish to understand the mathematical origin of the FEM methods used in solving various physical situations such as heat/mass transfer and solid mechanics

Perfect Course !\n\nI recommend it to everyone who is interested in mathematics and physics.

The course was was great. However, illustrative examples solving real engineering problems could be introduced in lecture.

This is the best course as iam learning I so happy about your lecturer's\n\nIt is an wounder full experience that iam getting from you
