摘要: 在无限大微极正交各向异性弹性介质上覆盖弹性介质的弹性半空间的任意点上,作用着任意方向倾斜的移动荷载,给出了位移分量和应力的解析表达式.假设倾斜荷载是法向荷载和切向荷载的线性组合.利用Fourier变换采用特征值方法,并利用数值技术反演了Fourier变换.给出了铝环氧树脂复合材料的数值结果图形.Abstract: The analytic expressions for the displacement components and stresses at any point of an infinite micropolar orthotropic elastic medium with an overlying elastic half space as a result of moving inclined load of arbitrary orientation were obtained.The inclined load was assumed to be a linear combination of a normal load and a tangential load.The eigen value approach using Fourier transformas was employed and the transform was inverted by using a numerical technique.The numerical results were illustrated graphically for aluminium epoxy composite.
