中文摘要 | 本研究採行範圍積分法,使應用於二維橡膠材料裂縫之能量釋放率的有限元素計 算。此方法具有與積分區域無關的性質,因此在裂縫尖端附近不需要複雜詳密的網格,便能 有十分精確的計算結果。研究中並研討不同材料模型對計算結果的影響。同時,對於裂縫長 度、以及因為溫差變化所造成之熱載重對裂縫能量釋於率的影響,亦有所討論。 |
英文摘要 | The energy release rate for 2-D rubbery material problems is calculated by the domain integral method (DIM) with finite element solutions. The formulation has the advantage of patch independence so that a complicated finite element model around the crack tip is not required. The results of calculation due to different material models are investigated. The effect due to thermal loading, and crack length is also observed in the study. |
