Finite element analysis of gradient lattice structure patterns for bone implant design

Asliah Seharing, Abdul Hadi Azman, Shahrum Abdullah

The objective of this paper is to identify suitable lattice structure patterns for the design of porous bone implants manufactured using additive manufacturing.

Three-dimensional fatigue crack growth simulation of embedded cracks using s-version FEM

Shuji Tomaru, Akiyuki Takahashi

Since the most of structures and structural components suffers from cyclic loadings, the study on the fatigue failure due to the crack growth has a great importance. The purpose…

Effect of ballistic impact on Ti6Al-4V titanium alloy and 1070 carbon steel bi-layer armour panel

Sivaguru Shasthri, Venkatason Kausalyah

Ballistic missile-resistant impact panels have seen fair advancement over the years, especially in military applications. However, high cost, as well as a changing materials…

The implementation of extrapolation with smoothing technique in solving stiff ordinary differential equations

Noorhelyna Razali, Alias Jedi, Nuryazmin Ahmat Zainuri

Extrapolation is a process used to accelerate the convergence of a sequence of approximations to the true value. Different stepsizes are used to obtain approximate solutions…

Analysis of stress intensity factor for fatigue crack using bootstrap S-version finite element model

Muhamad Husnain Mohd Noh, Mohd Akramin Mohd Romlay, Chuan Zun Liang, Mohd Shamil Shaari, Akiyuki Takahashi

Failure of the materials occurs once the stress intensity factor (SIF) overtakes the material fracture toughness. At this level, the crack will grow rapidly resulting in unstable…

Hardening model of severe plastically deformed AA2024 by high-pressure torsion

Fauziana Lamin, Ahmad Kamal Ariffin Mohd Ihsan, Intan Fadhlina Mohamed, Cheeranan Krutsuwan Nuphairode

This paper aims to evaluate the validity of bilinear hardening model to represent the stress flow of high-pressure torsion (HPT)-strengthened lightweight material, AA2024.

Moisture absorption effects on the mechanical properties of carbon/epoxy composites

Siti Faizah Mad Asasaari, King Jye Wong, Mohd Nasir Tamin, Mahzan Johar

This paper investigates the influence of moisture absorption on the mechanical properties of carbon/epoxy composites.

Detection of high stress concentration zone using magnetic flux leakage method

Syed Muhamad Firdaus, Azli Arifin, Siti Norbaya Sahadan, Shahrum Abdullah

A tower crane mainly ensures the success or efficiency of building construction. Fatigue crack analysis is important for tower crane components to prevent any accidents to workers…

Effect of chewing and cutting condition for V-shape three-dimensional titanium miniplate for fixation of mandibular angle fractures (MAFs)

Ruslizam Daud, Xu Wenzhao, Ishak Ibrahim, Nur Saifullah Kamarrudin, Khairul Salleh Basaruddin, Fauziah Mat, Rohaizar Ismail

Miniplate shapes determine the fixation stability to promote best healing and osseointegration process of mandibular fracture. In clinical treatment, the common method used two…

Fatigue damage assessment of reinforced concrete beam using average frequency and rise angle value of acoustic emission signal

Noorsuhada Md Nor, Soffian Noor Mat Saliah, Khairul Afinawati Hashim

In civil engineering construction, the reinforced concrete (RC) structure is generally used and exposed to fatigue loading as it is in service. The assessment of the RC structure…
