本文介绍了试制的多头液压拘束度计的测试系统,并对带有刚性底板的抗裂试件的拘束度进行了研究,导出了一维和二维拘束试件拘束度的表达式;提出了一种定量确定钢材临界拘束度和临界拘束应力的简便的可变拘束抗裂试验方法。
In this paper, a test system of a trial hydraulic longitude restraint meter was introduced. The restraint degree of the cracked test specimen with a rigid backplane was studied. The expressions of restraint degree of the one-dimensional and two-dimensional restraint test specimens were derived.
