Column usually rests directly on top of a stone base without any physical connection in traditional timber structures. When timber structure is subjected to horizontal loads, rotation around the edge of column foot may occur with or without slippage of column. Columns rock with cyclic lift and reset. Compression deformation occurs to column foot due to the heavy vertical load of the structure and...
Ultrasonic nondestructive testing technique has been widely applied to rail inspection. Due to the influence of probe placement and the complex structure of the rail, current devices are limited in the ability of detecting most defects existing in the rail base. In this paper, the electromagnetic acoustic transducer (EMAT) is applied to the inspection of rail base defects. Wave modes in the rail base...
In this paper, we report the design, simulation and optimization of a novel polymeric out-of-plane electro-thermal micro-actuator. The electro-thermal micro-actuator consists of tri-layers: the passive Ni layer, an expanding SU-8 layer and a curling S-shaped Ni heater. The tri-layer actuator is accompanied with a suspended structure to produce an out-of-plane movement perpendicular to the substrate,...
The knowledge of the wall stress distribution in an intact abdominal aortic aneurysm (AAA) is required for assessing its risk of rupture. By simulation three dimensional (3D) models of AAA are usually generated in order to estimate the stress distribution. To evaluate the effects of wall thickness on AAA model reconstruction and stress distribution, herein we created and compared two 3D models of...
Fe3Al intermetallics and Q235 steel are bonded using vacuum diffusion bonding technology. The interfacial shear strength was measured and the stress of Fe3Al/Q235 diffusion bonded joint was analyzed using finite element analysis (FEA). The results indicate that interfacial shear strength increases from 39.9 to 112.3 MPa with the enhancement of heating temperature from 1000 to 1060°C. Also, shear fracture...
