摘要: 采用拉普拉斯-傅利葉變換和施密特(Schmidt)方法,研究了復合材料因熱流在裂紋周圍引起的熱應力,并對用環氧樹脂粘結的陶瓷-鋼板進行了數值計算.Abstract: Application of the Laplace-Fourier transforms and the Schmidt method, thermal stresses around two cracks of composite materials due to heat flow are determined.As an example,the thermal stress intensity factors around two cracks in a ceramic and steel bonded composite are calculated numerically.
