local dent meaning in English
局部凹陷
Examples
- The cause is that during the course of local dent , a large amount of energy is dissipated at the moment of impact
主要是由于局部凹陷在冲击瞬时就消耗了大量能量的缘故。 - It can be observed from experiment that the final whole deformations of the tubes take on the shapes of " v " , and " w " in certain condition . the local dents of the tubes are obvious . the critical velocities and plugging modes of penetrations can be obtained
从实验中可以观察到：管的整体残余变形为“ v ”形，在一定条件下，还可能为“ w ”形；有明显的局部凹陷，可以得到穿透时的临界速度，其穿透破坏形式为冲塞型。 - Although strict design calculations are made to guarantee the members have sufficient strength in their work life , yet dash and improper loads may damage them during construction and in service . these damages include elastic - plastic bending and local dent in the walls of the tube . in addition , corrosive medium such as atmosphere and contaminated water can also bring corrosion damage in the walls of the tube
虽然都经过严格的设计计算，以保证其在使用寿命期内有足够的强度，但在安装施工和使用期间，往往因受到冲撞和非正常荷载而产生弹塑性弯曲和凹陷等损伤，此外大气、受污染的水分等腐蚀性介质也可能在管壁上产生腐蚀损伤。 - It can be seen from the deformation courses of the tubes that the local dents firstly occur at the beginning of impact . with the growth of the dents , the stiffness decreases , and the rigid - body translations and the whole deformations take place . the initial kinetic energy of the missile decreases rapidly to approximate zero during the course of impact , and the energy is transferred to internal energy and kinetic energy of the tube
同时，也得到了一些实验中没有观察到的现象：从模拟的管梁的变形历程可以看出，在冲击瞬时，管梁先发生局部凹陷，随着局部凹陷的加大，管梁的抗弯刚度减小，然后太原理工大学硕士学位论文刚体平动和整体变形发生，而且速度越大，这种现象越明显;子弹的入射动能在撞击过程中急剧减小，撞击结束后减小到可以忽略不计。
