| 9. | Afterward the numerical method was used to decompose the inherited integration , so the matrix form of constitution equations was derived . then through utilizing the lagrange equation directly , the paper gets the finite element formula . to test the model , the paper calculate the osteoblast ' s dynamic response under near static load and sinusoidal load at a simple tension beam and a four point bending beam 针对单向拉伸和四点弯曲两种离体培养成骨细胞的装置,再根据实际情况,将培养基看成是一种多孔材料,而将成骨细胞看成是粘弹性体,利用自编的有限元分析程序分别计算了受拟静态载荷和受交变载荷下细胞的动力响应,结果很好地反映了细胞的粘弹性性质。 |
| 10. | Experimental and finite element analysis of three point bending ( tpb ) test were conducted . it is found material ' s anisotropy of anisotropic materials and poission ' s ratio of isotropic materials all had influence on contact deformation between specimen and fixture . so it is wise to get flexural properties using four point bending test 4 .通过试验和有限元分析发现,造成对三点弯曲试验测得的三维编织复合材料的弯曲模量远低于四点弯曲试验结果的原因:材料的各向异性和泊松比对于三点弯曲试验的压头和支座处的局部接触变形影响很大 |
