Homogenization of Griffith's Criterion for brittle Laminates [PDF]
arXiv, 2021 We consider a periodic, linear elastic laminate with a brittle crack, evolving along a prescribed path according to Griffith's criterion. We study the homogenized limit of this evolution, as the size of the layers vanishes. The limit evolution is governed again by Griffith's criterion, in terms of the energy release (of the homogenized elastic energy ...

Ultrahigh toughness polycrystalline ceramics without fading of strength [PDF]
arXiv, 2021 Zirconia ceramics have been known as a structural material with high fracture toughness and strength since Garvie et al. discovered phase transformation toughening in 1975 [1]. Although these mechanical properties are the most excellent among the advanced ceramics, the toughness has not yet reached the level of metallic materials.

Averaging-based approach to toughness homogenisation for radial hydraulic fracture [PDF]
arXiv, 2022 The homogenisation of the fracture toughness is considered in the context of a propagating hydraulic fracture. The radial (penny-shape) model is utilized, in order to incorporate the impact of the viscosity-toughness regime transition over time. A homogenisation strategy based upon temporal-averaging is investigated.

Toughness and spectral radius in graphs [PDF]
arXiv, 2023 The Brouwer's toughness conjecture states that every $d$-regular connected graph always has $t(G)>\frac{d}{\lambda}-1$ where $\lambda$ is the second largest absolute eigenvalue of the adjacency matrix. In 1988, Enomoto introduced a variation of toughness $\tau(G)$ of a graph $G$.

Strong, Tough and Stiff Bioinspired Ceramics from Brittle Constituents [PDF]
Nature materials, 13(5), 508-514 (2014), 2015 High strength and high toughness are usually mutually exclusive in engineering materials. Improving the toughness of strong but brittle materials like ceramics thus relies on the introduction of a metallic or polymeric ductile phase to dissipate energy, which conversely decreases the strength, stiffness, and the ability to operate at high temperature ...
