摘要
介绍了结合材料力学组合变形中的偏心拉压内容设计的偏心拉压实验项目,并利用两种偏心拉压试件分别测定试件偏心距e和材料的弹性模量E并与理论值进行比较,使实验与理论教学有机的结合,提高学生学习兴趣。
The experiments of eccentric tension/compression are designed on the basis of eccentric tension/compression of combined deformation in mechanics of materials in this paper.The eccentricity e and the modulus of elasticity E are tested by two kinds of eccentric tension/compression samples,and the results are compared with the theoretical values.The study is an organic combination of experiments and theoretical teaching,which increases the learning interests of students.
