1)  compressive plastic strain
压缩塑性应变
1.
The traditional viewpoint of existing heating process and neglecting melting phenomena in welding results in the error of considering compressive plastic strain in welding.
由于认为焊缝存在加热过程和忽视熔化现象的存在,导致传统观点认为的焊缝存在压缩塑性应变的错误。
2.
Residual stress elimination does not employ the tensile plastic strain to reduce,withdraw or compensate the compressive plastic strain,but to convert the residual elastic strain to a.
提出焊接残余应力形成和消除原理:焊接残余应力不是压缩塑性应变引起的,而是由于焊缝和近缝区金属在"力学熔点"及以下温度冷却收缩受阻产生的;消除焊接残余应力不是产生拉伸塑性应变以减少、抵消和补偿压缩塑性应变,而是将残余弹性应变转变为塑性应变;消除焊接残余应力并不是必须去除固有应变,部分去除或完全不去除固有应变也能完全消除残余应力。
3.
The traditional view that the distribution of residual compressive plastic strain across the wel.
焊缝不存在残余压缩塑性应变,只存在拉伸应变,焊缝和近缝区残余压缩塑性应变分布和大小的传统观点不成立。
2)  compressive plastic strain
压塑性应变
3)  plastic compressive deformation
塑性压缩变形
1.
The phenomena and principle of the equivalent plastic compressive deformation (EPCD) during the process of increasing temperature and holding temperature of solid-state welding of 40Cr to QCr0.
结果表明:等效塑性压缩变形是焊件在升温、保温过程中受约束压力作用不能胀大而产生的塑性变形的累积,它提供了形成固相焊接接头所必需的塑性变形。
4)  compressive plastic deformation
压缩塑性变形
1.
In this paper,the problems on compressive plastic deformation in the weld and the principle of welding stress and strain described by D.
讨论了焊缝是否存在压缩塑性变形问题和拉达伊D应力应变原理图存在的问题。
5)  plastic compression
塑性压缩
1.
To explore the compaction mechanism of soft inclusion soils for reference to construction and design,a compaction model is established based on the analysis of both pore space reduction and plastic compression of highly compressive material ingredients.
为探索软夹杂土体压实的机理和规律,指导软夹杂土体的压实施工和配方设计,从孔隙的减少和高压缩性材料的塑性压缩两个角度进行分析建立软夹杂土体的击实模型,推演其密度计算式;以泡沫塑料混合轻质土为例,利用室内试验测试模型参数,并对所建击实模型和计算式进行验证。
6)  compression strain
压缩应变

分子式:
CAS号:

性质:一种以恒定压缩面积来压缩试样的方法。将片状试样的中央部分放在有长方形截面积的两个模片之间加以压缩,这样,试样受压缩的面积是恒定的,可以很容易计算出真应力而不是公称应力。此外,这种压缩方法在应变增加时,模片和试样间的摩擦仍能保持恒定,而单轴压缩却不能做到这一点。本方法需要对边缘效应加以校正。
