Abstract (EN): An experimental and analytical investigation of the effect of size on the strength of composite laminates with central holes loaded in tension and compression is presented. Specimens with different hole sizes and with constant width-to-diameter ratios were tested is tension and compression under quasi-static loading and the strength reduction for increasing sizes was quantified. In addition, centered cracked specimens loaded in tension and in compression were tested to obtain the laminate fracture toughness. This laminate property is required for the strength prediction method. The applicability of available strength prediction methods (Whitney-Nuismer, Soutis-Fleck) [6, 7, 8] to simulate the effect of size on the strength of notched composites is discussed.
