Journal ArticleDOI
Potential Relationship between Design of Nickel-Titanium Rotary Instruments and Vertical Root Fracture
TL;DR: The stiffer file designs generated higher stress concentrations in the apical root dentin during shaping of the curved canal, which raises the risk of dentinal defects that may lead to apicalRoot cracking.
Journal ArticleDOI
Design of mechanical clinching tools for joining of aluminium alloy sheets
TL;DR: In this paper, the authors proposed a design method of mechanical clinching tools, which can be used to join aluminium alloy sheets in automobiles, based on the analytical model used to predict the strength of the mechanical clinched joint.
Journal ArticleDOI
Parametric study on mechanical clinching process for joining aluminum alloy and high-strength steel sheets †
TL;DR: In this article, the effect of process parameters on the joint characteristics of advanced high-strength steel DP780 and Al5052 alloy sheet in mechanical clinching process was investigated using finite element (FE) analysis.
Journal ArticleDOI
Design of hole-clinching process for joining of dissimilar materials – Al6061-T4 alloy with DP780 steel, hot-pressed 22MnB5 steel, and carbon fiber reinforced plastic
TL;DR: In this article, hole-clinching tools were designed based on the geometrical relationship between the forming volume and the joint strength, and practical experiments were performed to verify the practicality of the hole clinching process.
Journal ArticleDOI
Comparison of forces generated during root canal shaping and residual stresses of three nickel-titanium rotary files by using a three-dimensional finite-element analysis.
TL;DR: The study aimed to compare the stress distribution during simulated root canal shaping and to estimate the residual stress thereafter for some nickel-titanium rotary instruments, finding the original ProTaper design showed the greatest pull in the apical direction and the highest reaction torque from the root canal wall, whereas ProFile showed the least.
