项目摘要

1.Investigation of Thermal Stress-Focusing Effect Caused by Phase Transformation in Composite MaterialsThe elastodynamic response of the transformation-toughened ceramics under an instantaneous phase transformation has been investigated in several works. Some composite materials, such as Zirconia toughened ceramics, are remarkable material, which has a high strength, a high elastic modulus, and an improved toughness, etc. Most of the good qualities are common in many ceramic composite materials. These good qualities are made possible through the phase transformation of composite particles. The transformation toughening utilizes the stress-induced phase transformation of particles, which is accompanied by a volumetric expansion. In this study a phenomenological model is proposed to describe the situation, which involves a dynamic phase transformation in a spherical particle embedded in the infinite elastic matrix.2.Development of Properties in the Particulate Composite Materials Caused … More by the Thermal ShockIn this investigation we solve, in an exact manner, the effects of the thermal stress-focusing effect in a spherical inclusion embedded in an infinite medium by using the ray integrals. This investigation analyzes the stress-focusing effect caused by the instantaneous phase transformation in the spherical inclusion of Zirconia embedded in the infinite domain. By using the ray theory, the numerical results give a clear indication of the mechanism of stress-focusing effect in an inclusion embedded in the infinite elastic medium.3.Experimental Study of Stiss-Focusing Effect in a Spherical Inclusion by using YAG LaserWhen an infinite elastic medium with a spherical inclusion is suddenly subjected to an instantaneous phase transformation, stress waves occur at the surface of spherical inclusion the moment instantaneous transformation strains are applied. The wave may accumulate at the center and show the stress-focusing effects. The experimental study is the stress-focusing effect one in a spherical inclusion by using the impact heating of YAG Laser.

1.复合材料相变引起的热应力聚焦效应的研究相变增韧陶瓷在瞬时相变下的弹性动力学响应已经有多篇论文进行了研究。一些复合材料,如氧化锆增韧陶瓷,是一种令人瞩目的材料,具有高强度、高弹性模量、提高韧性等特点。许多陶瓷复合材料的大部分优良品质是共同的。这些优良的品质是通过复合颗粒的相变而实现的。相变增韧利用应力诱导的颗粒相变,伴随着体积膨胀。在这项研究中,提出了一个现象学模型来描述这种情况,这涉及到嵌入在无限弹性矩阵中的球形粒子的动态相变。热冲击对颗粒复合材料性能的影响本文用射线积分法精确地求解了嵌入无限介质中的球形夹杂物的热应力聚焦效应。本文分析了氧化锆球形夹杂在无限域中瞬时相变引起的应力聚焦效应。利用射线理论,数值结果清楚地揭示了嵌入无限弹性介质中的包裹体应力聚焦效应的机理。当含球形夹杂的无限弹性介质突然发生瞬时相变时,施加瞬时相变应变的瞬间,球形夹杂表面会产生应力波。波可能在中心积聚,并表现出应力聚焦效应。实验研究了YAG激光冲击加热在球形夹杂中的应力聚焦效应。少
