Analysis Of Stress Concentration Factor Around The Hole Of Syntactic Foam Tensile Specimens
Abstract
Syntactic foam composed of fused borosilicate glass microballoons and vinyl ester resin matrix represents
viability for using as lighter material in marine structure. Designing of syntactic foam with higher strength properties is
challenging since it is difficult to control the fracture of glass microballoon particles. As a result, the selection of good
combination of filler and resin should be considered in order to achieve acceptable strength properties. The focus of this
research is to investigate the stress concentration factor (SCF) of syntactic foam comparable with simulation result. The
analysis is performed using the strain gage method bonded near the hole area of uniaxial tensile specimens that are radially
inhomogeneous plates. The effect of hole with varying composition of fused borosilicate upon stress concentration factors are
analysed.
