Combined mode I - mode III fracture toughness of a high carbon steel

Scripta Metallurgica, 1989
Abstract 1. 1. Brittle materials exhibit minimum energy dissipation under pure mode I loading 2. 2. In these materials, the mode IIIcomponent essentially provides redundant plastic work and increases J totalc . 3. 3. This behavior contrasts with more ductile materials where combined mode I - mode III loading produces The minimum ...

A Suggested Procedure for Combined Mode I — Mode III Fracture Toughness Testing

Journal of Testing and Evaluation, 1990
Abstract Mode I fracture toughness testing is well developed and standards exist for determining both Mode I critical stress intensity factors and J integrals. However, combined Mode I — Mode III testing is not so well developed and no standards exist.

Fracture toughness of aged dental composites in combined mode I and mode II loading

Journal of Biomedical Materials Research, 2000
Resin-based laboratory dental composites for prosthetic restorations have been developed in the past years as a cost-effective alternative to conventional porcelain-fused-to-metal or full ceramic restorations. The fracture toughness at different stress states (K(Ic), K(IIc), and mixed-modes K(I), K(II) ) was assessed for three laboratory dental ...

Fracture toughness of polycrystalline tungsten under mode I and mixed mode I/II loading

Materials Science and Engineering: A, 1999
The fracture toughness of swaged polycrystalline tungsten was tested parallel and perpendicular to the swaging direction and under mixed mode I/mode II loading. The fracture mode is dominated by the microstructure and changed from all-transgranular cleavage in mode I to almost all-intergranular fracture in mode II. The mixed mode results can be related

Combined mode I-mode III fracture toughness of a spherodized 1090 steel

Acta Metallurgica et Materialia, 1991
Abstract The aim of this investigation was to determine the fracture behavior of a spherodized 1090 steel under combined mode I-mode III loading conditions. Suitably defined formulations of the J integral denoted Jic and Jiiic were used to characterize the elastic-plastic fracture of this steel.

Fracture toughness for mixed mode I/II of epoxy resin

Acta Materialia, 2005
We investigated the fracture locus and the direction of the crack initiation under mixed mode I/II for epoxy resin at room temperature. In order to obtain them over a whole mode mixity, we conducted asymmetric bending tests. We examined four common fracture criteria to compare them with the experimental results.

Mode-I Fracture Toughness Prediction of Diamond at the Nanoscale

Journal of Nanomechanics and Micromechanics, 2017
AbstractIn this paper, the fracture process of nanoscale diamond is analyzed using atomistic simulations and fracture toughness obtained using four different continuum fracture-mechanics theories.

Ceramic Matrix Composite Interlaminar Fracture Toughness (Mode I-II) Characterization

Volume 6: Ceramics; Controls, Diagnostics and Instrumentation; Education; Manufacturing Materials and Metallurgy; Honors and Awards, 2015
The objective of this effort is to develop and demonstrate innovative interlaminar Mode I and Mode II fracture toughness analysis and test methods for ceramic matrix composites (CMC). Currently, there are number of American Society for Testing and Materials (ASTM) test standards for CMC’s at both ambient and elevated temperatures, including ...
