Preliminary lectures on deformation and fracture of solids are given to the students at the school of engineering during the first semester of their first year. These lectures are just the entrance to produce engineering materials and structures but show the essential aspects related to mechanics. It should be extremely difficult for the students to have real images of deformation and fracture of solids since no demonstration to clearly show such concrete phenomenon is given to them during the lectures. So, the video materials as the useful and helpful assistant to the lectures have been prepared. Tensile tests on mild carbon steel specimens with notches or cracks, uni-axial compression of cancellous bone with sophisticated trabecular structure, cyclic compression of model femur with artificial joint, and so on were chosen as the subjects of the materials. Finite element analysis was also performed to show its smartness and feasibility for the accurate simulations of these experiments.
