由于钎焊是表现在温度与热短程,应变必须避免在钎焊和冷却这一合金。
Since brazing is performed at temperatures within the hot-short range, strain must be avoided during the brazing and cooling of this alloy.
与之相似,如果在约束态冷却过程中停止冷却并卸载,卸载应力-应变曲线首先呈线弹性关系,然后才出现应力平台。
Similarly, the unloading stress-strain curves exhibited a linear elastic response followed by a stress plateau if the constrained thermal cycle stopped upon cooling.
分析了浇注温度、落砂温度对温度场分布、冷却速度、应力和应变的影响。
The influence of pouring temperature and shakeout temperature on the temperature field distribution, cooling velocity, stress and strain was analyzed.
这个过程中的加热,成型和冷却将引进应变(通常称为应力)进入玻璃器皿。
This process of heating, forming and cooling will introduce strain (often referred to as stress) into the glassware.
以带气膜冷却孔的航空燃气涡轮发动机涡轮叶片为研究背景,引入了等效概念对密布小孔结构进行了详细的应力-应变分析。
An equivalent no-perforated plate concept is introduced in the stress-strain analysis for densely-distributed film cooling holes on turbine blades of gas turbine engines.
如果在冷却过程中发生正相变的时候停止冷却并加载,则加载应力-应变曲线只出现应力平台。
If the constrained thermal cycle stopped upon cooling while the forward martensitic transformation was in progress, the loading stress strain curves exhibited the stress plateau immediately.
针对钢板冷却发生翘曲变形的问题,利用热弹塑性有限元法对中厚板冷却过程的温度场及应力应变场进行数值模拟。
The temperature and stress-strain field of steel plate runout table cooling are simulated using thermo-elastoplastic finite element method.
较快注塑(到点):在填料过程中冷却较少,因此初始固化层较薄,由于剪应变稀少而粘性较低;
Faster injection (up to a point): less cooling during filling, hence a thinner initial frozen layer, lower viscosity due to shear thinning;
