Experimental evaluation of monotonic and cyclic fracture behavior using disk-shaped compact tension test and released energy approach
… and cyclic loading using the disk-shaped compact tension (DC(T)) test and a released-energy based approach. The standard DC(T) test was revised to facilitate both monotonic and cyclic loading tests, including some modifications of the test geometry and testing modes. The research was …

Dynamic Fracture of Adhesively Bonded Composite Structures Using Cohesive Zone Models
… data obtained from standard fracture test configurations, theoretical and numerical tools are developed to mathematically describe non-self-similar progression of cracks without specifying an initial crack. A cohesive-decohesive zone model, similar to the cohesive zone model known in …

Interfacial strength development in thermoplastic resins and fiber-reinforced thermoplastic composites
The objective of this study was to develop tests that could be used to characterize autohesive strength development in amorphous thermoplastic resins and fiber-reinforced thermoplastic prepregs. All tests were performed using polysulfone P1700 thermoplastic resin and AS4/P1700 graphite-polysulfone …

Properties of functionally graded concrete slabs
… the feasibility of developing a fracture test that was easy to perform in the field. The standard fracture test involves using a three-point beam setup (SEN(B)). The SEN(B) geometry is extremely difficult and time consuming to extract from the field and so a circular specimen, which could …

Peridynamic analysis of fatigue crack growth in fillet welded joints
… and crack growth. Two types of numerical tests are conducted to validate the peridynamic fatigue model. One is tensile test for the phase of crack nucleation and the other is compact tension test for the phase of crack growth. All results from numerical tests are compared with experimental …

Multiscale characterization of mechanical and fracture properties of cortical bone specimens
… a whole bone at the macroscale. Several fracture testing methods are available including the three-point bending test, the compact tension test and the double cantilever test. However, these methods are confined to the macroscopic scale. At the microscopic scale, Vickers Fracture Indentation was …

The effect of pre-strain on the fracture toughness of line pipe steel
… on toughness has been developed. The material tested in the experimental study was an API 5L X80 line pipe steel. Samples of the virgin material were subject to pre-strains of approximately 2.7 percent and 6.5 percent engineering strain. The lower level of pre-strain is similar to that in a …
