A Review of Dynamic Experimental Techniques and Mechanical Behaviour of Rock Materials
TL;DR: A review of the development and the state of the art in dynamic testing techniques and dynamic mechanical behaviour of rock materials can be found in this article, where a detailed description of various dynamic mechanical properties (e.g., uniaxial and triaxial compressive strength, tensile strength, shear strength and fracture toughness) and corresponding fracture behaviour are discussed.

Local impact effects of hard missiles on concrete targets
TL;DR: In this paper, a collection of empirical formulae to predict the penetration depth, scabbing thickness and perforation thickness is presented in both Imperial and SI units and the current status of various design codes is summarized based on a dimensional analysis, dominant non-dimensional parameters that may influence the local impact effects on concrete targets are obtained and then used to present some of the test data Various nose shape factors are compared and a unique definition of the nose shape factor is suggested Analytical models and numerical simulation methods for penetration are summarized Criticisms are made for the current understanding of

An interacting micro-crack damage model for failure of brittle materials under compression
Bhasker Paliwal,K.T. Ramesh +1 more
TL;DR: In this paper, a model for brittle failure under compressive loading with an explicit accounting of micro-crack interactions is developed for the case of uniaxial compression under constant strain rate loading, and the model provides a natural prediction of a peak stress (defined as the compressive strength of the material) and also of a transition strain rate.

Fracture Mechanics of Ceramics
TL;DR: In this article, a linear-elastic fracture mechanics can be applied to describe the failure behavior of small flaws in ceramic materials, which is caused by the extension of small faults.

Elastic moduli of a cracked solid
TL;DR: In this paper, a self-consistent method for the elastic moduli of bodies containing randomly distributed flat cracks, with or without fluid in their interiors, is proposed and general concepts are outlined for arbitrary cracks and explicit derivations together with numerical results are given.
Dynamic Fracture Mechanics
TL;DR: In this article, basic elastodynamic solutions for a stationary crack and asymptotic fields near a moving crack tip are presented. But they do not consider the elasticity and rate effects during crack growth.

The failure of brittle solids containing small cracks under compressive stress states
Michael F. Ashby,S.D. Hallam +1 more
TL;DR: In this article, a model for the growth and interaction of cracks in brittle solids under compressive stress states is developed, where a critical stress is required to initiate crack growth: it depends on the initial crack length and orientation, the coefficient of friction and on the stress state.
