摘要: 应用复合材料经典层合板理论,分析了强化复合地板刚度计算,并使用电阻应变片测得试件在受轴向拉伸或纯弯曲载荷时,其上、下表面的应变x和y,从而对柔度系数的实验值和预测值,正则化柔度系数与弹性常数进行了验证。结果表明,预测值与实验值相对误差较小,建立的强化复合地板刚度计算模型能较好地符合实际情况。图1表5参8Abstract: On the basis of the classic theory on plywood,the stiffness computation model of laminated flooring was built in this paper. In the model test,the test specimens were under single axial tensile load or pure bending moment load,the strain of face and back plies,x and y were obtained through strain gage,so the experimental and theoretic value of some compliance coefficients were tested. The result from experiments showed the stiffness model could have a good prediction of the stiffness of laminated flooring.[Ch,1 fig. 5 tab. 8 ref.]
