چکیده

Abstract SiC fiber-reinforced matrix composites (SiC f /SiC) with 2D woven fabric as preform were tested under compression in-situ X-ray computed tomography. The microstructure and damage evolution of the material continuous loading levels accurately revealed by image reconstruction CT data. There inhomogeneous pores in /SiC composite because un-uniform fiber distribution preform. result also showed that had obvious non-linear characteristics its compressive load–displacement curve, modes included transverse cracking, interlayer longitudinal bundle fracture. Matrix cracking tended to occur near or holes material, number cracks was relatively high compared cracks.

Cumulative Fatigue Damage Under stepwise Tension-Compression Loading

Rock structures are subjected to cyclic tension-compression loading due to a blasting, earthquake, traffic and injection-production in underground storage case. Therefore study the fatigue behavior of rock samples under this type of loading is required. In this study, the accumulated fatigue damage for a Green Onyx rock sample which consisted of only one mineral composition with two-step high-l...

Effect of strain rate on the compression behavior of a woven glass fiber/SC-15 composite

Strain rate dependent compression behavior of a plain-weave S-2 glass fabric SC-15 epoxy (rubber toughened resin) composite plate, currently studied as the backing plate for composite armor applications, was determined in the through-thickness direction (normal to the fiber plane) in the strain rate regime of 1 10 4 to 1:1 10 s . In the studied strain rate regime, the modulus and failure streng...
