摘要
摘要 评估了在层间裂纹开裂（模式 I）和剪切（模式 II）联合加载下层状玻璃-环氧复合材料裂纹生长数值模型的可靠性。根据实验确定的标准（DCB 和 ENF）和非标准（SLB 和 OLB）方法，计算了单独加载和组合加载模式 I 和 II 下的层间抗裂参数值，并将 Benzeggagh-Kenane 方程中的指数作为层压环氧玻璃复合材料的材料常数。利用该参数，并在线性弹性断裂力学和虚拟裂缝闭合法框架内使用 ANSYS 应用软件包，对 SLB 和 OLB 型试样在不同模式组合加载模式下的层间抗裂性进行了有限元数值建模。通过在有限元网格中设置与给定裂纹生长轨迹长度相对应的最佳元素数量，数值建模能够以最少的计算量充分准确地计算出裂纹开始生长时的极限载荷，并且实验确定的抗裂参数与计算得出的抗裂参数之间具有良好的一致性。
Experimental Assessment of the Adequacy of Numerical Modeling of the Interlayer Crack Resistance of a Laminate Glass-Epoxy Composite under Combined Loading Mode I/II
Abstract—The reliability of numerical modeling of crack growth in a laminate glass-epoxy composite under combined loading by opening (mode I) and shear (mode II) of an interlaminar crack was assessed. According to experimentally determined standard (DCB and ENF) and nonstandard (SLB and OLB) methods for the values of interlayer crack resistance parameters under individual and combined loading modes I and II, the exponent in the Benzeggagh-Kenane equation was calculated as a material constant of a laminated epoxy glass composite. Using this parameter and using the ANSYS application software package within the framework of linear elastic fracture mechanics and the virtual crack closure method, the numerical finite element modeling of interlaminar crack resistance of SLB and OLB type specimens was carried out under a combined loading mode with a different fraction of modes. With an optimal number of elements in a finite element mesh corresponding to a given length of the crack growth trajectory, the numerical modeling provides sufficient accuracy in calculating the limit load of the beginning of crack growth with a minimum amount of calculations and good agreement between the experimentally determined and calculated crack resistance parameters.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
