In this paper, plastic flow behavior and micro structural evolution of Ti-6Al-4V alloy in temperature range of 750-1050 °C and strain rate range of 0.001-0.1 (S-1) in isotherm compression condition were investigated. The purpose was to estimate activation energy of globularization of lamellar structure and analyze this process kinetically. True Stress-strain curves obtained at the temperat...
With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...
Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and connections. Therefore, elimination of residual drift and increasing the plastic rotation capacity for the connectors in the panel zone are required. The main purpose of this s...
This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...
