Bioresorbable stents (BRS) are an alternative to existing bare-metal (BMS) and drug-eluting (DES), aiming reduce the short- long-term complications in cardiovascular interventions. A combination of biodegradable polymers a composite scaffold is promising solution improve BRS flexibility strength, which currently limited by material properties polymers. In this study, mechanical performance comprised two layers with four different combinations polylactic acid (PLA) polycaprolactone (PCL) was...
An investigation of the fatigue behaviour re-entrant auxetic structures made aluminium alloy AA 7075-T651 is presented in this study. The analysed represent a new class cellular that show anomalous deformation responses such as negative Poisson's ratio. In proposed work, influence unit cell orientation on crack path and life was studied using experimental computational approaches. Low Cycle Fatigue (LCF) tests were performed at load control with ratio 0.1 tension. LCF five loading levels...
ABSTRACT This paper presents a numerical simulation of micro‐crack initiation that is based on Tanaka‐Mura nucleation model. Three improvements were added to this First, multiple slip bands where micro‐cracks may occur are used in each grain. Second improvement deals with coalescence by extending existing along grain boundaries and connecting them into macro‐crack. The third handles segmented generation, not nucleated one step like model, but instead generated steps. High cycle fatigue...
The plate heat exchanger (PHE) is a component that provides to be transferred from hot water domestic cold without mixing them with high efficiency. Over the lifetime of PHE, cyclic pressures act on brazing points and plates, this may lead fatigue failure. behaviour designed using copper-brazed 316L stainless steel, was investigated in study. First, tests under load ratio R = 0.1 were performed Vibrophore 100 testing machine obtain S-N curve analysed brazed joint. Based obtained experimental...
Bioresorbable stents (BRS) represent the latest generation of vascular scaffolds used for minimally invasive interventions. They aim to overcome shortcomings established bare-metal (BMS) and drug-eluting (DES). Recent advances in field bioprinting offer possibility combining biodegradable polymers produce a composite BRS. Evaluation mechanical performance novel BRS is focus this study, based on idea that they are promising solution improve strength flexibility single material Finite element...
A computational model for analysing the tooth deflection of polymer gears is presented in this paper. Because have less stiffness compared to metal gears, proposed approach considers a comprehensive analysis determine most suitable numerical model, i.e., number teeth that should be modelled. The developed has been evaluated on spur gear pair, where pinion made POM meshed with support steel. Material properties were assigned linear elastic characteristics gear, while was characterised by...
