Interaction of elastic waves by an interfacial Griffith crack

Moving Interfacial Griffith Crack between Bonded Dissimilar Media

The plane strain problem of determining strain energy release rate, crack energy, and crack-opening displacement (COD) for a moving Griffith crack at the interface of two dissimilar orthotropic half-planes is considered. The problem is reduced to a pair of singular integral equations of second kind which have finally been solved by using Jacobi polynomials. Graphical plots of the strain energy ...

Diffraction of Vector Elastic Waves by a Finite Crack.

Communicated June 30, 1964 The problem of the diffraction of obliquely incident scalar waves by finite slits and strips with various boundary conditions has been considered previously.' Reference may be made to the work of other authors on the diffraction of scalar waves by finite slits.2 The problem of the diffraction of obliquely incident vector elastic waves by a clamped finite strip has als...

Diffraction of Scalar Elastic Waves by a Finite Crack.

arc, with two end-plates energized by a common negative voltage referred to the central arc. Note that these are actually experimental results for a real central uranium arc, operating at about 50 volts, for more than 100 tests, at total arc currents of 1-100 amperes. The floating cylinder was about 4 feet in diameter, and the negatively energized circular end-plates were separated by about 3 f...

Scattering of SH-waves by a Griffith crack in a long strip at asymmetric position

The scattering of SH-waves by a Griffith crack in an infinitely long elastic strip situated at an asymmetric position has been analyzed. Applying Fourier transform, the mixed boundary value problem has been reduced to the solution of dual integral equations which finally has been reduced to the solution of a Fredholm integral equation of second kind. The numerical values of stress intensity fac...
