预应变 meaning in English
prestrain
Examples
- A mean strain or prestrain, as in fig. 83, can under certain conditions reduce the subsequent fatigue life .
一个如图83所示的平均应变或预应变，在某种情况下，能够缩短以后的疲劳寿命。 - Experimental study of impact location method for piezoelectric smart structure
时效处理温度对预应变碳素钢疲劳极限的影响 - And to the specimens with various pre - deformation , the larger strain is , the higher temperature at which recovery stress start and the maximal stress arrive is , and the lower recovery stress is
不同预应变下，预应变越大，开始出现回复力及达到最大回复力的温度越高，而最大回复力却越小。 - The lath width of martensite can be fined noticeably by pre - strained quenching at non - dynamic recrystallization to approach nanometer magnitude ( the average width is 120nm )
采用非动态再结晶温度下的预应变-淬火，提高马氏体相变形核率，可以超细化马氏体的板条晶片宽度，使之接近纳米量级水平(平均宽度达到120nm ) 。 - The a3 steel is a kind of plastic material which we commonly used in our daily life and teaching , but there is not much study of mechanical behaviour of the material after pretorsion and pretension intensify at present
A3钢是我们日常生活和教学中常用的一种塑性材料，但对于这种材料在扭转预应变和拉伸预应变后的力学性能目前研究的不多。
