Time-harmonic sources in a generalized thermoelastic continuum

The disturbance due to a time-harmonic normal point load and thermal source in a homogeneous isotropic thermoelastic, half-space is investigated by ap plying the Hankel transform technique in the context of generalized theorie s of thermoelasticity. The inverse transform integrals are evaluated using Romberg integration with adaptive stepwise after using the results from suc cessive refinements of the extended trapezoidal rule followed by extrapolat ion of the results to the limit when the step-size tends to zero. The displ acement, temperature, and stresses so obtained in the physical domain are c omputed numerically and presented graphically in Figures 1-12 in different situations for Aluminium-epoxy composite material. A comparison of the resu lts for different theories of generalized thermoelasticity is also presente d.
