| Consider a space containing a hole of radius R and an crack of length A. Establish the Cartesian coordinate systems at the circular inclusion and the interfacial crack respectively. Let the coordinate origins be at a distance h below the surface. The distance is d between the hole and the crack. The governing equation can be written in the following simplify form if wave impacts on the space at a certain angle. |

a hole of radius R and an crack of length A→ a hole with a radius of R and an crackwith a length of A; Let the coordinate origins be at a distance h below the surface.→the coordinate starts below the surface with a distance of h; The distance is d between the hole and the crack.→The distance between the hole and the crack is d; simplify form →simplified form 或者The governing equation can be simplied as follows:.... ......其實(shí)還有一些。 你這個顯得很羅嗦。畫個圖,標(biāo)上尺寸,然后再列出參數(shù)如: radius of hole: R length of crack:A distance between the hole and the crack: d height from bottom to the surface :h ...... 我也不專業(yè)啊,不能保證全正確。僅供參考。 |
