摘要:
应用黏弹性有限变形理论,研究了不可压黏弹性圆柱体受到均匀温度场作用下的热空化问题.分别对圆柱实体和预存微孔的圆柱体两种情形进行讨论,建立了问题的非线性数学模型.数值计算结果证实了分叉问题可视为预存微孔半径生长的理想模型,得到了微孔半径随时间增长的动态变化曲线,并讨论了外界温度场、初始微孔半径、材料参数以及轴向伸长对微孔半径增长规律的影响.
Abstract:
Apply the viscoelastic finite deformation theory to study the problem of hot cavitation of a noncompressible viscoelastic cylinder under a uniform temperature field. We discuss the cylindrical case and the pre-deposited cylinder case. The numerical results confirm that the bifurcation problem can be regarded as an ideal model for the growth of predeposited pore radius, and the dynamic change curve of micropore radius grows with time. The effects of the external temperature field, initial pore radius, material parameters and axial elongation on the growth law of micropore radius are discussed.
