摘要

摘要根据脆性材料中被圆孔削弱的无限层的组合加载实验数据，建立了由能量准则决定的临界状态模型。破坏准则与通过相互作用弧和线性尺寸的自由能流有关。所提出的方法允许我们反映临界外部载荷对曲率半径的依赖性。我们提出并实施了确定线性尺寸值的程序。利用已知的实验结果，获得了 GVVS-16 石膏层的引入线性参数的估计值。

Brittle Fracture of an Elastic Layer with a Defect in the Form of a Circle under Biaxial Loading

Based on experimental data on the combined loading of an infinite layer weakened by a circular hole in a brittle material, its critical state, determined by the energy criterion, is modeled. The failure criterion is related to the free energy flow through the interaction arc and the linear size. The proposed approach allows us to reflect the dependence of the critical external load on the radius of curvature. A procedure for determining the value of the linear size is proposed and implemented. Using known experimental results, an estimate of the introduced linear parameter for a layer of GVVS-16 gypsum was obtained.

期刊介绍： Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
