The objective of this study was to examine the effects of the hydroxyapatite (HA) reinforcement morphology and content on the fatigue behavior of HA reinforced high density polyethylene (HDPE). To this end, HDPE was reinforced with 20 and 40 vol% of either HA whiskers or an equiaxed HA powder, and tested in four-point bending fatigue under simulated physiological conditions. The fatigue life, m...

This paper numerically investigates the flexural response of concrete beams reinforced with steel and four types Fiber-Reinforced Polymers (FRP), i.e., Carbon FRP (CFRP), Glass (GFRP), Aramid (AFRP), Basalt (BFRP). The responses forty two boundary conditions (simply supported over-hanging beams) were determined using ABAQUS. Subsequently, finite element models validated experimental results. Ev...

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...
