RISDimensionless Compliance With Effective Modulus in Crack Length Evaluation for B أ— B Single Edge Bend Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In ASTM standard E1820, the crack size, a, may be evaluated during Jintegral or cracktip opening displacement (CTOD) resistance testing using the measured crackmouth opening displacement (CMOD) elastic unloading compliance ...
Damage Model Prediction of Crack Initiation and Propagation in Five Fracture Geometries for X80 Pipeline Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Test specimens used to calibrate damage-mechanics models are designed to produce a range of stress triaxialities and Lode angles to accurately capture the fracture envelope of the metal. Many of these specimens have lower ...
