In this paper，the application of the computer mathematics calculation software Matlab in the teaching of material mechanics is analyzed. It is shown in an example how the computer analysis can be integrated with mechanics material teaching under the background of education reforms, which can release the contradictions between the reduction of class hours and teaching content and can improve the teaching effects of material mechanics. It is improved the introduction of Matlab can not only inspire the study taste in students, but also improve the acquaintanceship with engineering problems and the abilities of mechanics modeling and mathematics analyzing, which can also help them analyze and solve the practical mechanics problems effectively in the future.
