A model for the deformation of an elastic solid reinforced by embedded fibers is presented in which elastic resistance of the fibers to bending is incorporated. Within the framework of strain-gradient elasticity, we formulated the equilibrium equations and necessary boundary conditions which...

A reconstruction methodology based on different-phase-neighbor (DPN) pixel swapping and multigrid hierarchical annealing is presented. The method performs reconstructions by starting at a coarse image and successively refining it. The DPN information is used at each refinement stage to freeze...

A dynamic 2D axisymmetric CFD model, coupled to a 1D bed model, has been developed to simulate the production of lime in a rotary kiln. The model simulates heat transfer caused by radiation, convection and conduction between the gas, wall, and bed to determine the axial bed temperature in the...

Microstructures on insect wings can promote directional drop shedding, and the local orientation of these structures is expected to facilitate drop removal. However, microstructures may exhibit very different orientations at different locations on the wing. Using the march fly Penthetria...

The dynamic fracture of natural polyphase ceramic (granite) blocks by high-speed impact at 207 m/s, 420 m/s and 537 m/s has been investigated. An electromagnetic railgun was used as the launch system. Results reveal that the number of fragments increases substantially, and the dominant length...

Abstract—Spark Assisted Chemical Engraving (SACE) is a non-traditional micro-machining technology, with one of its unique characteristics being the physical distance relationship between the tool and workpiece during machining. Previous papers have illustrated that maintaining space between the...

Fatigue-induced crack initiation and growth are common in cyclically loaded structures. Crack reduces the structures' strength and increases the risk of failure. Engineers have been using degradation models like Paris' law to relate crack length to the magnitude of the applied load to schedule...

This work demonstrates a novel multi-configurable three-state electrothermally-actuated microgripper. The state of the gripper refers to the electrical configuration of the hot and cold arms as well as the mechanical mode of operation. The gripper has three basic electrical configurations and...
