Section snippets Division of the elastic and plastic zones around a tunnel It can be shown from the theory of elasticity that, without the presence of the normal support pressure on the cavity wall, the radial stress σr and the tangential stress σθ in the rock around a circular tunnel su...
The plane strain condition was applied for any tunnel cross-section because the tunnel length in the longitudinal direction was much larger than that in the horizontal direction. (2) The rock surrounding the tunnel was simplified as a homogeneous and elasto-plastic medium, while the lining was co...
where Ei is the elastic modulus of the corresponding element and μiμi is the Poisson ratio of the corresponding element. The stress state before the rock burst accident is named as pre-state stress field (PSSF), after being affected by a trigger stress field (named TSF; a high probabili...
Plastic gears also exhibit a lower elastic modulus and mesh stiffness, leading to greater deflection under load.Despite the similarities between metal and plastic gears, the engineering and design of plastic gears involve additional considerations specific to their material properties....
In fact, because of surface roughness and the high elastic modulus of most metals, the contact pressure between asperities at short length scale can be very high even when the nominal contact pressure is low. Thus for metals in the area of real contact some plastic flow will almost always ...
modulus, and impact strength [36]. Examination of the impact of mechanical recycling processes on recycled CRD plastic properties compared to virgin plastic resin can reflect the physical and chemical aging of the plastic. In addition, the presence of additives in post-consumer CRD plastics must be...
The paper deals with the bearing capacity of circular glass panels with metal fasteners and plastic layers in point supporting glass structures. Influences of the elastic modulus and thickness of plastic layers and the inner diameter of the fastener on the stress state and capacity of circular glass...
It has been a long-standing materials science challenge to establish structure-property relations in amorphous solids. Here we introduce a rotationally non-invariant local structure representation that enables different predictions for different loading
