springback is one of the most common and important issues in metal forming area. due to it depends on variety of parameters, it is hard to predict. hence, in this paper, the effect of continuum damage mechanics (cdm) based on the lemaitre isotropic unified damage lawon springback was investigated. swift’s hardening law was employed to describe isotropic hardening behavior.the result showed cons...

Abstract Hydroxyapatite has been synthesized as a bone graft material by analyzing the membrane made according to cytotoxicity test and bending test. The method used is dry ball milling. Cytotoxicity testing was carried out making isolated osteoblast cells cultured in 75 cm 2 cell flask containing minimum of essential media. Based on test, it found that hydroxyapatite not toxic with viability a...

Semi-Circular Bending (SCB) Test is a fast and accurate three-point bending test, which was originally used in rock mechanics. SCB test is going to be an accepted test method for asphalt concrete pavements. Different asphalt-mixture property-values such as tensile strength, stress intensity factor and fatigue can be obtained by this test. In this study, static and dynamic tests including SCB te...

This thesis investigates the reliability of printed conductors on flexible substrates under cyclic bending. The topic is approached by studying the effects of several key design parameters on the bending lifetime of printed conductors under dynamic loading. In this thesis, the test specimens with various cross-sectional geometries were printed on different plastic and paper substrates. The test...
