TAILIEUCHUNG - Calculation of stress intensity factors for an interfacial notch of a bi-material joint using photoelasticity

In this paper, the stress intensity factors (SIFs) for an interfacial notch in a bi-material joint have been calculated using the experimental method of photoelasticity. A bi-material Brazilian disc specimen with a central interface notch was employed to determine the SIFs for different mode mixities. | Calculation of stress intensity factors for an interfacial notch of a bi-material joint using photoelasticity Engineering Solid Mechanics 1 2013 149-153 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Calculation of stress intensity factors for an interfacial notch of a bi-material joint using photoelasticity M.

A bi-material Brazilian Received in Revised form disc specimen with a central interface notch was employed to determine the SIFs for different September 14 2013 mode mixities. In this approach SIFs were calculated experimentally for an Al Polycarbonate Accepted 22 September 2013 Available online bi-material Brazilian disc specimen and two different loading angles . modes I and II 23 September 2013 dominated loading conditions . The results of experimental approach were then compared with Keywords the numerical values of finite element method. Experimental results were in good consistency Photoelasticity with the numerical values. Stress intensity factors Bi-material joint Bi-material notch Brazilian disc specimen 2013 Growing Science Ltd. All rights reserved. 1. Introduction Bi-material joints are increasingly used for various engineering applications. A stress singularity may develop at an interface corner when the bonded materials are subjected to mechanical and or thermal loading. Since failure is most likely to be initiated from a singular point it is therefore important to properly characterize the singular stresses around the interface notches. The stress intensity factors characterize the singular stress field close to the notch tip. Hence calculating the
