| 摘 要： | 在材料力学实验中引入夹层梁纯弯曲实验，运用材料力学的理论方法对夹层梁弯曲正应力理论计算方法进行推导．通过采用电测法测量指定截面上的弯曲正应力，将实验值与理论计算值比较．经过比较可知，夹层梁纯弯曲时满足平面假设条件，理论计算公式可行．

| Abstract: | The sandwich beam pure bending experiment is introduced in the experiment of material mechanics.Based on material mechanics theories,the sandwich beam bending normal stresses academic calculation is deduced.By measuring the bending normal stresses of appointed section with the electricity and measure method and comparing the experiment value with theories value,the plane surface supposed condition can be satisfied and the academic calculation formula can go when the sandwich beam purely curves. |
