查询词典 material time

Superior material life is based on economic development, which, however, at the same time has negative influences on human beings."Health problem" is one of them. It has been proved in practice and research in all countries of the world that it is effective to prevent "health problem" by improving people's physical constitution.

优越的物质生活来源于经济的发展，然而，经济发展在给人们带来充裕物质条件的同时，也给人类带来了负面影响，"健康问题"就是其中之一。

The research results show as follows. As plastic deformation increases, the Young's modulus of material continuously changes. This variation law is able to be described using a piecewise linear function .Hardening model and whether the variation is considered or not make great effet on springback prediction. It is proved that the springback prediction result which adopts the elastic-plastic constitutive model based on INLK hardening model and the variation of Young's modulus is considered, is more close to experimental result. After the sheet metal undergoes multiple bending, the corner radius and bending height also affect springback greatly.But the effect trend is different. At the same time, the reliability of springback research using numerical simulation is proved.

研究结果表明：材料弹性模量随塑性变形的变化是不断变化的，该变化规律可用分段线性函数进行描述；强化模型及考虑弹性模量变化与否对回弹预测有很大的影响，基于INLK强化模型和考虑弹性模量变化的弹塑性本构模型对回弹的预测结果与试验最接近；多次弯曲中圆角半径与弯曲高度对板料变形后的回弹有较大影响，但影响趋势不同；证明了数值模拟方法对回弹研究的可靠性。
