Parameterization, statistical measurement and numerical modeling of fluctuated meso/micro-structure of plain woven fabric GFRP laminate for quantification of geometrical variability

This paper proposed a stochastic multiscale modeling method by parameterization and quantification of the fluctuated meso/micro-structure of plain woven fabric glass fiber reinforced plastics (GFRP) fabricated by hand layup. The experimental results of static tensile tests of 25 specimens made by 5...
