查询词典 composite hypothesis

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.

得到如下结论：(1)相同的吸湿性，在30％PVF(颗粒体积分数：Particle volume fraction，PVF)前增加PVF，层间脱胶损伤值显著增加；此后损伤值的增加趋于平缓；(2)保持层间强度和PVF不变，层间脱胶损伤随吸湿率的增加而接近线性增加；(3)FCC(面心立方：Face-centred cubic，FCC)模型层间脱胶损伤的预测结果和实验数据基本吻合；同时此模型可以用于预测牙齿填充材料三点弯曲实验的临界载荷。4、建立理想牙齿修复结构，利用有限元方法研究了同时考虑聚合收缩和吸湿膨胀耦合作用下的填充修复材料和粘结界面层材料性能对牙齿修复结构的力学行为的影响，得到如下结论：(1)低弹性模量的牙齿填充修复材料能限制天然牙组织的位移，但天然牙组织的位移与粘结界面层的弹性模量无关。
