Tough double-bouligand architected concrete enabled by robotic additive manufacturing [PDF]
Nature CommunicationsNature has developed numerous design motifs by arranging modest materials into complex architectures. The damage-tolerant, double-bouligand architecture found in the coelacanth fish scale is comprised of collagen fibrils helically arranged in a bilayer ...

Experimental evaluation of CTOD in constant amplitude fatigue crack growth from crack tip displacement fields [PDF]
Fracture and Structural Integrity, 2017 In the current work an experimental study of the crack tip opening displacement (CTOD) is performed to evaluate the ability of this parameter to characterise fatigue crack growth.

Crack shielding in non-planar and frictional discontinuities under mixed-mode loading [PDF]
MATEC Web of Conferences, 2019 In this paper, a two-dimensional model to describe the non-planar features of crack morphologies is presented. The model accounts for frictional tractions along the crack surfaces by considering an elastic-plastic-like constitutive interface law ...

Growth of inclined fatigue cracks using the biaxial CJP model [PDF]
Fracture and Structural Integrity, 2015 The CJP model of crack tip stresses is a modified version of the Williams crack tip stress field which takes account of simplified stress distributions that arise from the presence of a zone of plastic deformation associated with the crack flanks and ...
