The development and testing of simulation software based on variational principles to examine the behavior of structures undergoing large scale elastic deflections is described. The programmes are used in the design of micro mechanical beams for packaging applications, specifically in the domain of passive alignment of optical components. The fabrication process is described for 5 μm thick sili...

This research effort is focused on the development of large angle, out-of-plane bimorph MEMS micromirrors fabricated in the PolyMUMPs foundry process. Based on design constraints of the PolyMUMPs process, current designs fabricated do not meet the requirements to enable large angle optical steering. Through Comsol modeling and simulation, several post-processing techniques were discovered that ...

Generalizations of the well-known Bassetti and Erskine formula to include tilt angle and non-Gaussian particle distributions, as well as centroid deflections, are derived.

Due to the low specific strength of bamboo oriented strand boards compared with commonly used wooden building materials, reasonable and novel cross-section designs columns fabricated from as structural members were investigated. An axial compression experiment was carried out on full-scale characterize ultimate behaviors under a concentric load. The bearing capacities solid, hollow five-core sa...

The use of fiber reinforced polymer (FRP) for flexural strengthening concrete (RC) beams has become a popular technique. Significant amount work is available on the short-term behavior RC strengthened with near-surface mounted (NSM) However, their time-dependent behavior, specifically under high service temperature, not yet been addressed. This paper presents an experimental to evaluate NSM car...

The application of engineering in the field civil is growing rapidly, requiring more productivity, creativity, and innovation from structural engineers, especially engineering. To get optimal cross-sectional dimensions, magnitude forces or loads acting on structure needs to be analyzed for beams columns. Under influence working load, moment bearing capacity will deform evenly throughout element...
