459/GMB: Bulk Modulus and Failure

Bulk Modulus at 23C:

  • from ultrasound = 3.14 GPa
  • from dilatometer = 3.04 GPa

Density at 23C:

  • by weight and dimensions = 0.69 g/cc
  • 56vol% filler based on filler density = 0.32 g/cc

KIC from pre-cracked 3-pt bend samples at 23C = 1.07 ± 0.04 MPa-m1/2
