Effects of retention groove location and dimensions of threaded glass fiber post on the maximum retention force of the restorative system and the maximum equivalent stress in the root were numerically investigated. Results show that the retention groove can effectively enhance retention ability and reduce the stress in the root. And the maximum retention force of the restorative system can be increased...
This paper presents a study of spring-back in the free bending metal forming process, and the analytical model of free bending process is constructed. Different punch radius, die-lip width and sheet thickness are varied to study their effect on spring-back. Abaqus/Explicit is used to simulate the forming process, and Abaqus/Standard is used to simulate the spring-back process. The analysis shows that...
