Mechanical properties of PLA/HA composite for Coronary Stent application by powder processing
Chin, Man Soon (Universiti Malaysia Perlis (UniMAP), 2016-06)The risen in mortality cause by coronary heart disease (CAD) leads to intervention of procedure such as bypass surgery and percutaneous coronary intervention (PCI) with or without stenting. Nevertheless, the idea of procedure ... -
Multi-phase smoothed particle hydrodynamics (SPH) modelling for laser micromachining
Noorhafiza, Muhammad, Dr. (Universiti Malaysia Perlis (UniMAP)School of Manufacturing Engineering, 2014-05)This invention overcomes the problem to model the laser micromachining process by introducing meshless method. Conventional modelling methods using generated mesh have been problematic in capturing the melt splashing or ... -
Surface modification of 316L stainless steel by using pulsed laser
Phuah, Yong Zhen (Universiti Malaysia Perlis (UniMAP), 2016-05)Coronary stent is a mechanical medical devices design to open the arteries that have been affected by coronary artery disease (CAD). Blood vessel obstruction is the result of atherosclerosis by the buildup of smooth ... -
Understanding the behaviour of pulsed laser dry and wet micromachining processes by multi-phase smoothed particle hydrodynamics (SPH) modelling
Noorhafiza, Muhammad, Dr.; Rogers, Benedict, Dr.; Li, Lin (IOP Publishing, 2013-03)A smoothed particle hydrodynamics (SPH) numerical model is developed to simulate the three-phase laser micro-machining process for medical coronary stent manufacture. The open-source code SPHysics is used to model the ...
