Title:
The effect of microthread design on magnitude and distribution of stresses in bone: A three-dimensional finite element analysis
Year:
2018
Abstract:
Background: The researches regarding the influence of microthread design variables on the stress distribution in bone and a biomechanically optimal design for implant neck are limited. The aim of the present study is to compare the eff

Title:
Prediction of machining chatter in milling based on dynamic FEM simulations of chip formation
Year:
2018
Abstract:
Chatter vibration is a major obstacle in achieveing increased machining performance. In this research, a finite element model of chip formation in a 2D milling process is used to predict the occurrence of chatter vibrations, and to inv

Title:
An efficient scanning algorithm for improving accuracy based on minimising part warping in selected laser sintering process
Year:
2019
Abstract:
In the selective laser sintering (SLS) method, layers of powder are scanned by a laser beam and sintered. The thermal gradients created by laser heating and the subsequent cooling of the sintered sections results in thermal stresses an
