摘　　要：将有限元分析软件ANSYS引入材料力学实验教学中,丰富了教师的教学手段,使材料力学实验中抽象化的假设、结论以图形的形式展示出来,提高了学生的理解力。以材料力学实验中的纯弯曲实验为例,利用ANSYS建立了梁的模型,并施加相应的约束和载荷,得到相应的应变图、应力图和变形图,并将ANSYS分析结果与实验结果进行分析对比,进一步验证了梁在纯弯曲变形时应变、应力的分布规律。The finite element analysis software is introduced into the experimental teaching of material mechanics,which enriches the teaching means of teachers.The abstract hypothesis and conclusion in the experiment of material mechanics are displayed in the form of graphics,which improves the students’ comprehension.Taking the pure bending experiment in material mechanics as an example,the model of the beam is established by ANSYS,the corresponding constraints and loads are applied,and the corresponding strain,stress and deformation diagrams are obtained.The ANSYS analysis results are compared with the experimental results,the distribution of strain and stress of the beam under pure bending deformation is further verified.
