Orientation and loading condition dependence of fracture toughness in cortical bone
TL;DR: In this article, fracture toughness at crack initiation was determined for bovine cortical bone under tension (mode I), shear (mode II), and tear (mode III) for both longitudinal and transverse fracture.

A Micro?Macro Approach to Modeling Progressive Damage in Composite Structures
TL;DR: In this paper, a finite-element-based method for modeling progressive damage in fiber-reinforced composites is presented, based on the simple idea that the nodal forces of an element of a damaged composite material can be modified to reflect the general state of damage and loading.

Failure Analysis of Bolted Composite Joints Exhibiting In-Plane Failure Modes:
TL;DR: In this article, the Damage Zone Model (DZM) is applied for simultaneous in-plane, net-tension, and shear-out failure analysis of T300/914C graphite/epoxy [0/90/±45,]-type laminates containing a single, perfect-fit, finger-tight, bolt-loaded hole.

Fracture behavior of laminated metal-metallic glass composites
Yang Leng,T. H. Courtney +1 more
TL;DR: In this paper, the crack growth behavior of metallic glass in laminated metal-metallic glass composites was investigated and compared to the cracks in monolithic metallic glass, and it was found that an extrinsic factor, i.e., matrix bridging, makes the major contribution to increased crack growth resistance and a limiting crack opening displacement model interprets the experimental data quite well.

Equivalent Damage and Residual Strength for Impact Damaged Composite Structures
TL;DR: In this article, structural durability and damage tolerance of aircraft-composite structures is determined not only in the design process but also when the aircraft is in operational use, not only for the aircraft design process, but also for the operational use.

Stress Fracture Criteria for Laminated Composites Containing Stress Concentrations
J.M. Whitney,R.J. Nuismer +1 more
TL;DR: In this paper, two related criteria based on stress distribution are presented for predicting the uniaxial tensile strength of laminated composites containing through the thickness discontinuities of a general shape.

A stiffness derivative finite element technique for determination of crack tip stress intensity factors
TL;DR: In this article, a finite element technique for determination of elastic crack tip stress intensity factors is presented, based on the energy release rate, and the solution for only a single crack length is required, where the crack is 'advanced' by moving nodal points rather than by removing nodal tractions at the crack tip and performing a second analysis.
Journal ArticleDOI
Relationships between the J-integral and the crack opening displacement for stationary and extending cracks
TL;DR: In this paper, the relationship between the J-integral and the crack opening displacement δt is obtained by exploiting the dominance of the Hutchinson-Rice-Rosengren singularity in the crack-tip region.
