Ti-6Al-4V triply periodic minimal surface (TPMS) structures with biomorphics scaffold designs are expected to be the most promising candidates for many biological applications such as bone implants. Fracture is the main failure mode of Ti-6Al-4V cellular structures at room temperature. However, there is currently less investigation on general analysis about the fracture mechanism of Ti-6Al-4V T...

the main aim of this paper is to find the optimum shape of arch dams subjected to multiple natural frequency constraints by using an efficient methodology. the optimization is carried out by charged system search algorithm and its enhanced version. computing the natural frequencies by finite element analysis (fea) during the optimization process is time consuming. in order to reduce the computa...

This paper presents the calibration in laboratory of a weigh-in-motion sensor. The sensor has shape and external dimensions bump speed is mounted on road as well. was designed using finite element analysis (FEA) Computer Aid Design (CAD) programs. made sheet steel its components were welded together. Strain gauges elastic element. A FEA simulation static operation performed. then installed an I...

The lack of integrated design tools for Surface Acoustic Wave (SAW) devices has led us to develop tools for the design, modeling, analysis, and automatic layout generation of SAW devices. These tools enable rapid development of wireless SAW sensors. The tools developed have been designed to integrate into existing Electronic Design Automation (EDA) tools to take advantage of existing 3D modelin...

Gear failure is considered the main alarming and undesirable event in gearboxes. Usually, cracks happen by fatigue caused due to cyclic loading. Fatigue stress focused on teeth root because of small tooth fillet radius. This causes progressive damage gear which failure, hence, a damaged gear. work shows numerical framework identify quantify cracks' existence at spur gears. The problem numerical...

In 2021, Indonesia planned to build high-energy accelerator electrons for the sterilization of medical instruments. With transfer technology from Russia like civil engineering, architecture, electrical, mechanical, control system, and instrumentation. But some several core technologies electron reviews cavity material, strength material cavity, vacuum radiofrequency are not provided. For this r...

Abstract Finite-element analysis (FEA) for structures has been broadly used to conduct stress of various civil and mechanical engineering structures. Conventional methods, such as FEA, provide high fidelity results but require the solution large linear systems that can be computationally intensive. Instead, Deep Learning (DL) techniques generate significantly faster than conventional run-time a...

GaN nanowires (NWs) were synthesized through a vapor-liquid-solid (VLS) process. Based on structural analysis, the c-axis of the NW was confirmed to be perpendicular to the growth direction. Nanogenerators (NGs) fabricated by rational assembly of the GaN NWs produced an output voltage up to 1.2 V and output current density of 0.16 µA cm⁻². The measured performance of the GaN NGs was consistent ...
