Element Analysis

An investigation of die temperature changes and the heat transfer coefficient during hot forging of titanium alloy has been carried out using experiments and a thermal-plastic coupled finite element analysis. Hot Ti-6A1–4V rings were forged between two heated flat dies made of Inconel alloy IN718. The bottom die was instrumented with high-response thermocouples on its surface and subsurface. The recorded temperatures were analysed and used to determine the interface heat transfer coefficient between the die and the workpiece in conjunction with the thermal-plastic coupled finite element analysis using a reverse algorithm. The coefficients determined were then used in a finite element model for the analysis of the upsetting process and the results produced were in good agreement with the experimental data.

Element Analysis

Using of forceps during labors and vaginal delivery accomplished operative deliveries in some circumstances. Forceps may induce fractures in the neonatal skull if excessive force is applied to it during an operative delivery. Therefore, newborns may be affected by forceps. The aim of this study was to investigate the effects of different curve angles and materials of the blades of forceps on neonates during labor or delivery for gynecologists and obstetricians using a finite element analysis (FEA). Computer models of the forceps, neonate’s scalp, and skull, were generated for the FEA. Moreover, the use of different materials (stainless steel and titanium alloy) and three different angles of the blades of forceps (20[Formula: see text], 40[Formula: see text], and 60[Formula: see text]) on a newborn’s head were simulated in a biomechanical analysis. The results indicate that a larger curve angle of the blades of forceps can decrease the stress and pressure on the neck of the newborn but may lead to rotation toward the posterior side. Moreover, forceps made of a lower Young’s modulus material can also reduce the stress and pressure on the neck of the newborn. It is hoped that this research can provide a more reasonable reference for manufacturers to design better medical equipment such as forceps in the future for obstetricians and gynecologists to use to attenuate the stress and pressure on the neck of a newborn.

Tc4 Titanium Alloy

Using ABAQUS finite element analysis software, the bending model of TC4 titanium alloy was established to study the stress distribution and obtain the maximum compressive displacement by limiting its yield strength. Therefore, the applicable properties of the materials are evaluated to provide a basis for material optimization.
