T-spline based XIGA for fracture analysis of orthotropic media
Fracture analysis of orthotropic cracked media is investigated by applying the recently developed extended isogeometric analysis (XIGA) (Ghorashi et al., 2012) using the T-spline basis functions. The signed distance function and orthotropic crack tip enrichment functions are adopted for extrinsically enriching the conventional isogeometric analysis approximation for representation of strong dis...
متن کاملIntersonic Crack Propagation in Bimaterial Systems
This paper describes experimental observations of various phenomena characteristic of dynamic intersonic decohesion of bimaterial interfaces[ Two separate but complementary optical methods are used in con! junction with high!speed photography to explore the nature of the large!scale contact and mach wave formation at the vicinity of running cracks in two di}erent bimaterial systems[ Theoretical...
متن کاملFast crack growth along interfaces
Analyses of dynamic crack growth along interfaces are discussed. The material on each side of the bond line is characterized by an elastic constitutive relation. A cohesive surface constitutive relation that allows for the creation of new free surface is also specified across the bond line. The resistance to crack initiation and the crack speed history are then predicted without invoking any ad...
متن کاملIntersonic Crack Propagation along Interfaces: Experimental Observations and Analysis
-The isochromatic fringe patterns surrounding an intersonically propagating interface crack are developed and characterized using the recently developed stress field equations. A parametric investigation is conducted to study the influence of various parameters such as the crack-tip velocity and the contact coefficient on the isochromatic fringe patterns. It has been observed that the crack-tip...
متن کاملShear Dominated Transonic Interfacial Crack Growth in a Bimaterial-i. Experimental Observations
In this work we describe a series of impact experiments performed on PMMA/4340 steel edge cracked bimaterial plates. Specimens were impacted at 20 m SK’ in a one point bend configuration using a high speed gas gun. Dynamic interfacial crack propagation was observed using the optical method of Coherent Gradient Sensing and high speed photography. Very high crack tip accelerations (IO’ m SF’) and...
