Combined Mode I and Mode II Fracture of Monolithic Ceramics

Journal of the American Ceramic Society, 1993
The mode I, mode II, and combined mode I–mode II fracture behaviors of a coarse‐grained silicon nitride, a fine‐grained silicon nitride, and an alumina were investigated. These ceramics were fractured from two types of fracture initiating flaws: small surface flaws and large single edge precracks.

Rate-Sensitivity of Mode I and Mode II Fracture of Concrete

MRS Proceedings, 1985
ABSTRACTFor rational and accurate analysis of concrete structures subjected to impact or impulsive loads the knowledge of crack propagation under such dynamic loads is essential. Cracks frequently propagate under mixed-mode (opening and sliding: mode I and mode II) conditions.

A mixed mode fracture specimen for mode II dominant deformation

Engineering Fracture Mechanics, 1984
Abstract Several theories have been proposed for the failure of metals, as well as for the angle of crack propagation in mixed mode loading. In order to demonstrate the validity of these theories, the majority of tests have been carried out with an oblique crack placed in a uniaxial stress field. Better testing conditions may be achieved by placing a

Mixed Mode II-Mode III Fracture of Adhesive Joints

Journal of Composites Technology and Research, 1995
This paper presents approximate closed-form expressions for the local energy release rate in Mode I, Mode II, and Mode III along the idealized straight crack front of a cracked generalized adhesive joint. The development is based on beam theory, the J-integral, and a beam-on-an-elastic-foundation model.

Fracture Process in ± θ Laminates Subjected to Mode II Loading

Strength of Materials, 2002
This work studies the behavior of a multidirectional laminate under Mode II loading. We describe the process of delamination in a reinforced composite of glass/epoxy. The stacking sequence (plies orientation [± θ] was selected to minimize the coupling effects. The Mode II interlaminar test under three-point bending and cantilever flexure using ENF (End

A Compact Mode II Fracture Specimen

1986
A compact Mode II fracture specimen together with its loading frame is analyzed and tested. This system is a further development of an earlier circular Mode II fracture specimen presented by the authors. For fatigue precracking in two different loading configurations, formulas relating the Mode I stress intensity factor, applied load, and specimen ...

Mixed-mode-I/II fracture of polytetrafluoroethylene

Materials Science and Engineering: A, 2007
The current work deals with mixed-mode-I/II fracture in polytetrafluoroethylene (PTFE). Mode-I fracture in PTFE 7C has previously been shown to exhibit strong phase dependence with a brittle-to-ductile transition associated with the room temperature phase transitions.

Mode I and II fracture of adhesive joints

The Journal of Strain Analysis for Engineering Design, 1984
The compliance method is used to determine strain energy release rates in mode I and II fracture of adhesive bonded joints. A strong dependence of the strain energy release rates upon the adhesive thickness is found. Standard compact tension and compact shear specimens are used.

Mode II fracture toughness of stitched composites

19th AIAA Applied Aerodynamics Conference, 2001
Currently End Notched Flexure (ENF) specimens are used to determine the effect of stitching on the Mode II fracture toughness of laminated composites. In ENF tests the delamination does not open, but slides. This makes it difficult to locate the crack-tip as the crack propagates and hence to estimate the length of crack propagation.
