Predicting the crack initiation fracture toughness for a crack along the bimaterial interface
Three Point Bend (3PB) bimaterial specimens of PMMA/PC were made by joining the two materials using friction welding. The specimens were tested and the crack initiation loads were recorded to evaluate the K using ASTM standard E 1820-01. Stress field in the crack tip vicinity was studied using finit...

| description | Three Point Bend (3PB) bimaterial specimens of PMMA/PC were made by joining the two materials using friction welding. The specimens were tested and the crack initiation loads were recorded to evaluate the K using ASTM standard E 1820-01. Stress field in the crack tip vicinity was studied using finite element IC analysis of the specimen model. Normal and shear stresses were recorded for a series of nodes ahead of the crack tip at (2=0°). SIF values were calculated using these stress values and it was found that the stresses at
a certain distance lying outside the process zone provide a SIF value matching to that of experimental fracture
toughness of the specimen under study. Based upon the experimental evidence and finite element analysis, a
simple step by step procedure is proposed to calculate the fracture toughness of bimaterials for a complex stress
field. |
