Strain gage methods for measuring the opening mode stress intensity factor, KI
James W. Dally,Robert J. Sanford +1 more
TL;DR: This paper developed expressions for the strains in a valid region removed from the crack tip, and indicated procedures for locating and orienting the gages to accurately determine KI from one or more strain-gage readings.

On the measurement of dynamic fracture toughnesses — a review of recent work
TL;DR: In this article, the influence of dynamic effects on test procedures for measuring the crack arrest toughness and the impact fracture toughness is analyzed, and it is shown that these dynamic effects can be significant: for cracks at arrest the stress condition is still dynamic and not static although the crack velocity has become zero.

Elastic stress intensity factors evaluated by caustics
TL;DR: In this paper, the most important theoretical techniques for the solution of plane elasticity crack problems and the evaluation of stress intensity factors were reviewed by Paris and Sih, Sih et al. in the first volume of this series.
Journal ArticleDOI
Analysis of the optical method of caustics for dynamic crack propagation
TL;DR: In this paper, the elastodynamic crack tip stress field is used to establish the exact equations of the caustic envelope formed by the reflection of light rays from the surface of a planar solid near the tip of a propagating crack.

Transverse shear effects for through-cracks in an elastic plate
W. Yang,L. B. Freund +1 more
TL;DR: In this paper, the state of stress in a thin elastic plate which contains through-cracks is studied with a view toward assessing the influence of transverse shear on the crack tip stress and deformation fields.
