1) constraint facet
约束面
2) out-of-plane stress constraint
离面约束
1.
The crack tip fields and out-of-plane stress constraint of the specimens were analyzed using three dimensional elastic-plastic theory.
以三维弹塑性断裂理论为基础,对有限厚度板裂纹端部应力场、三维应力约束进行了分析,通过对不同厚度、不同初始裂纹长度在不同温度下三点弯曲试件的断裂韧性测试断口观测和理论分析获得如下结果:离面约束对裂尖应力场及断裂韧性有强烈的影响;断口均产生分层裂纹,其位置、大小和数量与试样厚度、温度和裂纹初始长度有关;温度较低时,分层裂纹距主裂纹根部一定距离,分层裂纹宽度较小,对厚度效应影响较小;温度较高时,分层裂纹首先出现在主裂纹根部,分层裂纹宽度较大且充分张开,降低了试样的有效厚度。
3) unilateral constraint
单面约束
1.
Differential variational principles of systems with unilateral constraints in non-inertial reference frame;
非惯性系中单面约束系统的微分变分原理
2.
Perturbation to symmetries and adiabatic invariant of Birkhoffian systems with unilateral constraints;

3.
Lie symmetries and conserved quantities of third-order nonholonomic systems with unilateral constraint in phase space are studied.
研究相空间中具有三阶线性单面约束的非完整系统的Lie对称性与守恒量。
4) constraint plane
约束平面
5) restrain curved surface
约束曲面
1.
In the light of the principle that the optimum solution of a structure must occur at the boundary of feasible domain, limiting search scope in the restrain curved surface, with the result that the original restrain extreme value problem could be transformed non-restrain one, we can solve the problem using more simple non-restrain optimum method,this method does be boundary search one.
边界搜索法是根据结构优化最优解必定出现在可行域边界上的原理,将搜索范围限定在约束曲面上,使原来的约束极值问题转化为无约束极值问题,因而可用比较简单的无约束优化方法来求解。
6) out-of-plane stress constraint factor
离面约束
1.
Based on three-dimensional finite element analyses,the effect of different notch angles,plate thickness and crack length on stress intensity factors(SIF) and out-of-plane stress constraint factors(T_z) are revealed and the scale of 3-D constraint area is also analyzed.
研究结果显示:当缺口张开角小于60度时,不同缺口的应力强度因子和离面约束因子的分布基本一致,角度的影响不明显。
