K. Viswanathan et U. Sharma, STRESS-CONCENTRATION DUE TO A FINITE RIGID RIBBON IN THE PRESENCE OF A FINITE KINKED CRACK - SH CASE, International journal of engineering science, 33(8), 1995, pp. 1171-1181
In this paper we discuss the stress-concentration problem when a plane
wave strikes a finite rigid ribbon in an infinite medium in the prese
nce of an inclined (kinked) crack of finite length. Chebyshev polynomi
al expansions are used for the solution of the governing integral equa
tions which are singular and are not otherwise easily amenable for sim
ple solution. Numerical results are included to give the effects of va
rious parameters on the stress intensity factors particularly at the r
igid ribbon ends. The model is chosen to provide some insight towards
the stress states near the asperities (hard regions) that seems to pla
y a significant role in seismic fault propagation in realistic media.
The solution also incorporates possible rigid body motion of the inclu
sion.
