Journal ArticleDOI
Suggested Methods for Determining the Dynamic Strength Parameters and Mode-I Fracture Toughness of Rock Materials
TL;DR: The properties of rocks under dynamic loading are important for the study of a whole range of rock mechanics and rock engineering problems, including blasting, protective design, explosives storage, rock bursts and seismic events as discussed by the authors.
Journal ArticleDOI
Printable properties of cementitious material containing copper tailings for extrusion based 3D printing
TL;DR: In this article, an environmental friendly cementitious mixture that is compatible with an extrusion-based printing process was proposed, where the authors investigated the six replacement ratio of tailing to sand from 0% to 50% and developed a single nozzle printing system.
Journal ArticleDOI
Numerical simulation of blasting-induced rock fractures
Guowei Ma,Xinmei An +1 more
TL;DR: In this paper, the authors implemented the Johnson-Holmquist (J-H) material model into the commercial software LS-DYNA through user-subroutines to simulate the blasting-induced rock fractures.
Journal ArticleDOI
Mechanical anisotropy of aligned fiber reinforced composite for extrusion-based 3D printing
TL;DR: In this article, an optimal basalt fiber content was determined basing firstly on suitable printability and then on mechanical performance using a self-developed 3D printer for extrusion of the cementitious material and also for mechanical enhancement of fiber alignment along the print direction.
Journal ArticleDOI
Modeling complex crack problems using the numerical manifold method
TL;DR: In this paper, complex crack problems such as multiple branched and intersecting cracks are studied to exhibit the advantageous features of the numerical manifold method, which is quite suitable for modeling discontinuous problems.
