Dynamic Mixed Mode Fracture.

Abstract

A newly developed data reduction process was used to reevaluate dynamic photoelastic results and to extract dynamic stress intensity factors, K(I)dyn and K(II)dyn, associated with curved and branched cracks in fracturing Homalite-100 plates. A branching stress intensity factor approximately 5 times the fracture toughness was identified for this material. Moderate to severe crack curvings were associated with a K(I)dyn and K(II)dyn ratio as low as 0.05, but with positive remote stress component, sigma (ox). (Author)
