Silicon nitride is a widely used industrial ceramic, specifically for dynamic loading applications because of its special mechanical and material properties. The investigation of the underlying mechanisms which lead to these properties is experimentally ch ...
Using a spectral resolution of the elastodynamic boundary integral equations, this poster is presenting the effect of tougher heterogeneities along a planar fracture plane. A centered crack propagating along a 1-D heterogeneous interface under mixed-mode l ...
Rock mass boreability is a comprehensive parameter reflecting the interaction between rock mass and a tunnel boring machine (TBM). Many factors including rock mass conditions, TBM specifications and operation parameters influence rock mass boreability. In ...
A discrete element model is proposed to examine rock strength and failure. The model is implemented by UDEC which is developed for this purpose. The material is represented as a collection of irregular-sized deformable particles interacting at their cohesi ...
As a second part of this series, the present study also addresses the water resistance of joints obtained by friction welding. Here, the mode II fracture is in focus, that is, 4-points end-notched flexure specimens (4-ENF) were investigated with various mo ...
Fiber-reinforced polymer (FRP) composites are increasingly used in many load-bearing
structures. Joints are the most critical structural elements as they often become the weak links
in engineering structures. Bonding and bolting are two of the main joini ...
The importance of the effect of ground abrasivity on the performance of a tunnel boring machine (TBM) is important for many tunnelling projects. In recent years, many abrasivity devices have been developed to measure soil abrasivity for specific conditions ...
Using an elastodynamic boundary integral formulation coupled with a cohesive model, we study the problem of a dynamic rupture front propagating along an heterogeneous plane. We show that small-scale heterogeneities facilitate the supershear transition of a ...
The mixed-mode fatigue and fracture behaviors of adhesively-bonded pultruded glass fiber-reinforced polymer joints are presented in this chapter. These behaviors are based on experimental investigations using asymmetric mixed-mode bending specimens. In suc ...
In this paper, experiments are carried out to study the quasi-static and dynamic fracture behaviour of sedimentary, igneous and metamorphic rocks. The notched semi-circular bending method has been employed to determine fracture parameters over a wide range ...
