局部强度 meaning in English

local strength

The multi - purpose tester developed here is aim at testing the mechanics performance of the brittle material , which bases on modular design thought , it contains several modules as the machinery load component , platform of supporting , the function modules and the software system , they can be combined in different function modules to satisfies the need of different application situation . the tester can be used to measure not only general material properties such as elastic modulus , ultimate strain , strength , hardness and toughness , fatigue properties but also various special properties such as the local strength , and surface residual stress at the different location of the brittle component with non - destructive methods . thus the security and reliability of the brittle component can be evaluated and predicted
本文基于模块化设计思想,研制了一台专门针对脆性材料力学性能测试的多功能脆性材料试验仪,其主要包括机械加载模块、支撑平台、功能模块、测控系统、软件系统等模块,通过对这些模块的不同组合可实现不同的功能及满足不同应用场合要求;系统除了具有测试脆性材料的弹性模量、极限应变、强度、硬度、韧性等常规性能外,还具有无损测试玻璃构件不同位置的局部强度和表面预应力,进而对玻璃构件的安全可靠性和寿命进行预测等功能。
