针对实际工程中常见的含圆孔和椭圆孔的树脂基复合材料板,建立基于Mathematica的计算模型,对带有圆形和椭圆孔的复合材料板,在不同荷载作用下进行计算,对两种孔形应力分布作比较。而且以两种不同材料含孔板为例,对不同荷载作用下的孔边应力进行计算,并对材料对孔边应力场的影响作较为全面的比较。为在实际工程中对孔形、材料以及所受外荷载进行合理选择提供理论依据。
Aimed at the common resin matrix composite plate with round or elliptical hole in practical engineering, the calculation model based on the Mathematica is set up. Through the calculation of composite plates with the round or elliptical hole under different load conditions, a comparison between two kinds of holes stress distribution is done. Moreover, taking two kinds of material for example, calculation of hole-edge stress under different load is carried out. The complete comparisons on the influence which material have on the hole-edge stress field are also carried out.It provides a theory for optimization of the structural shape and geometrical size of flywheel for energy storage.
