材料力学课程的教学中，应力集中问题是一个比较抽象想概念，为了便于学生理解，以及拓展学生综合运用多种手段和方法解决复杂问题的能力，文章将有限元数值手段运用到应力集中问题的教学中，让学生能直观地认识构件几何尺寸突变后，突变区域的应力分布也急剧发生变化，同时，也培养学生在没有解析解的情况下，综合运用数值模拟等手段解决具体工程问题的意识和能力。

In the teaching of material mechanics ,the stress concentration problem is a relatively ab‐stract concept of thinking ,in order to facilitate students'understanding ,and to expand the capacity of students comprehensive use of various means and methods to solve complex problems ,in this paper ,the numerical method is applied to the stress concentration problem in teaching ,so that students can intui‐tively understand geometry component mutation ,mutation of the stress distribution of a drastic change , at the same time ,but also cultivate the students without analytic solution ,the consciousness and ability of solving engineering problems using numerical simulation method .
