基于有限元分析的材料力学试验研究

摘要

For advancing students' capabilities of innovative experimental research, as means the finite element analysis is used for general experimental mechanics of materials. By analyzing numerical value of finite element in ANSYS software platforms, the corresponding stress, strain data and deformation diagram will be obtained. This lays a foundation for academic research of experiment. This paper compares the conventional electric method with finite element analysis by the normal-stress distribution of pure bending beams experiment. The comparing shows that the experimental results of the two methods are uniformity. In this paper, the study provides an effective way to experimental mechanics of innovative research.%为了提高学生创新型试验研究能力,在常规材料力学试验中引入有限元分析手段,通过在ANSYS软件平台上的有限元数值分析,获取相应的应力、应变数据及变形图,为基于试验的理论研究奠定基础.以纯弯曲梁正应力分布试验为例,对常规电测法和有限元分析法进行比较分析表明,2种方法得到的试验结果一致.本文的研究为材料力学试验创新研究提供了一种有效的途径.
