## Abstract Electrostatic discharge (ESD) on the metallic enclosure of electronic products normally generates unwanted radiated electromagnetic interference (EMI). The radiated EMI penetrates through the apertures on the enclosure and then couples to the circuitries inside the enclosure. This may c

β¦ Synopsis
Abatraet-The plane interaction between a circular elastic inclusion and an arbitrarily located and oriented crack or two equal length cracks subjected to a remote mode I stress is investigated. Stress intensity factors are presented for a variety of cracks-inclusion geometries. The solution technique is based on a singular integral method which uses distributions of edge dislocations to represent the cracks in the mathematical model. It is seen that this interaction can produce either an enhancement or a shielding effect on the stress intensity factor, depending on the positions and orientations of the cracks, the size of the inclusion, and the elastic constants of the matrix and the inclusion.

The problem of the scattering of time-harmonic elastic waves by a configuration of a crack and an adjacent inclusion embedded in a 2-D infinite elastic medium is investigated by the traction boundary integral equation (TBIE) method. The result of the formulation is a system of six coupled singular i
## Abstract Recent opinions on the effect of nonmetallic inclusions, especially sulfides, on the nucleation of pits, stress corrosion cracks, and hydrogenβinduced cracks are reviewed. The nonmetallic inclusions present in steels as impurities adversely affect the corrosion resistance of steels. Th
