1)  longitudinal limit constraint
轴向极限强约束
1.
At in vivo longitudinal limit constraint, the variation of the circumferential stress with time have the same phase and period with the curves of the pulsatile pressure, and the amplitudes have no change with the frequency.
结果表明,对某确定时刻,包含在运动方程中的惯性项对血管壁应力的影响很小,可忽略不计;在体轴向极限强约束下,血管壁周向应力随时间的变化曲线与压力曲线同相位和同周期,而且振幅不随频率的快慢而改变。
2)  terminal restraint
极限约束
1.
By analyzing the linkage of the cluster scale with the cluster effect,it puts forward that there is a terminal restraint between the cluster scale and the cluster effect,and the cluster effect increases with the expansion of the cluster scale before the cluster scale has not surpassed the terminal rest.
在分析集群经济和社会效益的基础上,从产业集群网络要素和结构关系的角度探讨了集群效应有限性的主要原因;分析集群规模与集群效应的关联性,提出在集群规模和集群效应之间存在着极限约束。
3)  axial restraint
轴向约束
1.
Parametric studies show that: the existence of the axial restraint causes an increase in the axial force before the column buckles and will reduce the buckling temperature of the column,however it has little influence on the column s .
提出了一种改进的Jezék方法,用于火灾升温下轴向约束钢框架柱屈曲后性能分析,高温条件下钢材的应力-应变关系考虑了钢柱屈曲后凸侧可能出现的卸载现象。
2.
Authors investigated the axial restraint on fire resistance of unprotected steel column with commercial finite element method(FEM) software MSC MARC Mentat.
采用大型商用有限元软件MSC MARC Mentat研究了钢结构柱所受轴向约束的刚度对抗火性能的影响,对无保护层钢结构柱的抗火性能进行有限元分析,分析结果与试验结果吻合较好。
3.
The effects of end-plate connection and axial restraint on the behaviour of steel beams are also attained.
得出钢梁的温度场分布、变形情况及端板连接、轴向约束对钢梁的影响。
4)  limit-restraint method
极限约束法
1.
A limit-restraint method is proposed based on modifying the finite element inverse approach.
基于对有限元逆算法的改进,提出了极限约束法。
5)  enhanced permission constraints
增强权限约束
6)  elastic axial restrain
弹性轴向约束
补充资料:侧向极限承载强度
分子式:
CAS号:

性质:用铆钉、螺杆、栓等办法将板材和板材之间搭接,或将板联接于其他部件上时,板材所能承受的最大的平行于板面的载荷除以它们的支撑面积所得的商值,单位MPa。这时,板材穿铆钉(或螺杆等)的孔洞一侧和铆钉柱之间因受局部挤压而发生塑性变形,最后导致板材被拉断。极限承载强度也称侧向极限承载强度。对该值的了解有助于选择铆钉直径和铆钉孔的布置,以利于整体工作强度。
