The paper addresses the problem of an interfacial crack in a multi-directional laminated beam with possible bending-extension coupling. A crack-tip element is considered as an assemblage of two sublaminates connected by an elastic-brittle interface of negligible thickness. Each sublaminate is modeled as an extensible, flexible, and shear-deformable laminated beam. The mathematical problem is reduced to a set of two differential equations in the interfacial stresses. Explicit expressions are derived for the internal forces, strain measures, and generalized displacements in the sublaminates. Then, the energy release rate and its Mode I and Mode II contributions are evaluated. As an example, the model is applied to the analysis of the double cantilever beam test with both symmetric and asymmetric laminated specimens.

“…Dois grupos distintos de CCMs são em geral encontrados nos diversos trabalhos publicados sobre o assunto: aqueles que contam com interfaces fortes entre as camadas e aqueles que contam com interfaces fracas. Os detalhes destes dois grupos de CCMs podem ser encontrados em [2]. Importante notar que, em ambos os casos, as camadas componentes do compósito devem ser rigorosamente selecionadas, de modo a se obter o produto final com as características desejadas.…”

Tailoring Toughness and Mechanical Reliability by Controlled Defects: Nature‐Inspired Composite Laminates of Laser‐Perforated Yttria‐Stabilized Zirconia

In general, strong materials also tend to be stiff but rarely tough. The other way around, tough materials are hardly particularly strong. [1] When it comes to materials that are simultaneously strong, stiff, and tough, nature provides outstanding examples, especially with respect to its limited availability of constituents, e.g., the unavailability of elemental metals. Examples that have seen a lot of attention in the last few years are tooth enamel, sponge spicules, and nacre, mother-of-pearl. These materials consist of a high content of parallel or concentrically aligned hard and stiff mineral phase that is surrounded by thin layers of bio-polymers like polysaccharides or proteins. [2][3][4][5][6][7][8] Mechanically, those layers of biopolymers both act as an adhesive to provide structural integrity and provide weak interfaces that allow for failure mechanisms like debonding, crack deflection, and pullout. [2,3,[7][8][9][10][11][12][13][14][15] The latter in turn consume large amounts of energy upon fracture and the right balance between strong adhesion for strength and stiffness on one hand and weak adhesion for energy dissipation during fracture on the other is one of the key features natural and synthetic materials possess to be simultaneously strong, stiff, and tough. [16][17][18] Analyzing such natural materials with respect to models for layered composite materials like those provided by Voigt, [19] Reuss, [20] Padawer and Beecher, [21] Gao et al., [22] or Begley et al., [23] one reaches the conclusion that for stiffest and strongest results, mineral and polymer need to be arranged strictly parallel to each other and to any applied load. This way, the mineral phase limits deformation and takes most of the applied load, thus defining stiffness and strength of a composite. [18,24] Regarding load bearing [*] Prof.
