Hindered Crack Propagation in Materials with Periodically Varying Young's Modulus—Lessons from Biological Materials†
TL;DR: In this paper, the authors derived a design criterion to obtain laminate structures without driving force for crack propagation perpendicular to the lamellae, and analyzed the driving force onto cracks propagating inside a material where the Young's modulus varies in a periodic way in a given direction.
Journal ArticleDOI
Bioinspired Design Criteria for Damage‐Resistant Materials with Periodically Varying Microstructure
TL;DR: In this paper, the authors show that the periodicity of the material properties is one of the dominant reasons for the high fracture resistance of these structures and their tolerance to short cracks.
Journal ArticleDOI
Equal channel angular pressing of metal matrix composites: Effect on particle distribution and fracture toughness
TL;DR: In this paper, an Al6061-20%Al 2 O 3 powder metallurgy (PM) metal matrix composite (MMC) with a strongly clustered particle distribution is subjected to equal channel angular pressing (ECAP) at a temperature of 370°C.
Journal ArticleDOI
Three-dimensional finite element simulation of a polycrystalline copper specimen
Andrei Musienko,A. Tatschl,K. Schmidegg,K. Schmidegg,Otmar Kolednik,R. Pippan,Georges Cailletaud +6 more
TL;DR: In this paper, finite element computations of an oxygen-free, high-conductivity copper multicrystal under monotonic tension are presented, where a series of polishing operations are used to reveal the real three-dimensional (3D) microstructure, so that the mesh is a full 3-D mesh.
Journal ArticleDOI
J-integral and crack driving force in elastic–plastic materials
TL;DR: In this paper, a configurational forces approach is used to identify a "plasticity influence term" that describes crack tip shielding or anti-shielding due to plastic deformation in the body.
