elastics

• The larger the elastic modulus, the greater the stress needed for a given strain .
  弹性模量越大，产生一定应变所需要的应力也越大。
• Two-dimensional collisions, both elastic and inelastic, may be demonstrated on this table .
  在这个桌上，可以演示二维的弹性和非弹性碰撞。
• There are two kinds of elastic waves in solids a compressional wave and a transverse wave .
  在固体中有两类弹性波，一类是压缩波，另一类是横波。
• A complete study of the propagation of shock waves in elastic solids is presently lacking .
  关于弹性固体中冲击波的传播，目前还缺少全面的研究。
• Elastic fibers usually occur as individual, refractile, branching, and anastomosing fibers .
  弹性纤维通常是单独的，折光的，分枝的及吻合的纤维。
• Characteristically, the strains in the plactic region are much greater than in the elastic region .
  很明显，塑性阶段的应变远大于弹性阶段的应变。
• Recently, the theory of dislocation in elastic solids has been applied to the earthquake problem .
  最近，弹性固体的位错理论已经被应用于地震问题。
• The theory of elastic stability is conspicuously absent from many books on the theory of elasticity .
  很多弹性理论书显然没有把弹性稳定性理论写进去。
• If we are dealing with incompressible elastic solids, some simplifications can be achieved .
  如果所处理的是不可压缩的弹性固体，我们就可以完成某些简化。
• However, momentum is always conserved in a collision, whether or not the collision is elastic .
  然而，不管碰撞是不是弹性的，在碰撞过程中动量总是守恒的。
