显微损伤
The rock damage model and the damage-coupling model suited to analyze the whole process of water jet breaking rock were established with continuum damage mechanics and micro damage mechanics.
运用连续损伤力学和细观损伤力学理论,建立了适用于水射流破岩全过程分析的岩石损伤模型以及宏细观损伤的耦合模式。
Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage.
微机械公司计划生产一种芯片,因为它只使用微小的机械开关,所以不会受到辐射损伤。
Beginning with the damage theory of micro-statistics, the constitutive model of corroded concrete under uniaxial compression is established which is proved by the experimental outcomes.
本文从微观统计的损伤理论出发,建立了腐蚀混凝土单轴受压本构模型,与试验结果较符合。
Objective To evaluate the damage caused by high intensity ultrasound(HIU)on tumor micro- vessels.

From the beginning of the definition of the damage variable, the definition methods of damage variable and their according damage models based on micro - and macro-theory.
文章从损伤变量定义的方法入手,讨论了基于宏微观理论的损伤变量定义方法及其相应的损伤模型。
microdamage(微损伤)指材料内部因应力作用形成的微观尺度损伤,通常无法通过肉眼或常规设备直接观测,需借助显微镜等工具检测。该概念在生物医学与材料科学领域具有重要应用,以下是具体解析:
在骨骼研究中,microdamage 指骨组织承受机械负荷时产生的微米级裂纹(长度约50-500微米)。这些损伤是骨骼疲劳的早期表现,积累过多会导致骨强度下降甚至骨折。例如:
在工程材料中,microdamage 表现为金属、复合材料等内部的微裂纹或空洞(尺度为纳米至微米级),由循环载荷或环境腐蚀引发:
"Microdamage"是由前缀micro-(意为“微小的”)和damage(损害/损伤)组成的复合词,通常指微观层面的损伤或微小损伤。以下是具体解释:
