Stress Concentration Factors of Some Fiber-Reinforced Composite Strips Containing a Hole under Tension or Bending.

Abstract

Factors of stress concentration were determined, experimentally and analytically, for boron/aluminum, boron/epoxy and FRP/ epoxy composite material strips containing a hole under tension or bending. In total, ten combinations of constituent modulus ratio, lamina orientation and fiber volume fraction, and three values of hole diameter to strip width ratio were investigated. Experimental values were obtained by means of electric resistance foil strain gages, and analytical results from the NASTRAN FINITE ELEMENT ANALYSIS. (Author, modified-PL)
