  Abstract

The finite element (FE) solutions of the smart (SMA: shape memory alloy fibre bonded) composite with and without crack are computed in this research. The structural model is derived mathematically considering the shear deformation effect, and the proposed functions maintain the necessary continuity of stresses. The numerical solutions are obtained via the computer code considering the blocking/recovery stress phenomenon (via marching technique) due to the inclusion of SMA fibre. The necessary correctness and the numerical results sensitivities are verified as priori. The solutions are showing an improvement of structural stiffness (decrease in deflections around 22–27% and 14–22% for the prestrain values 3–5% and 10–30% volume fraction of shape memory alloy fibre, SMA) due to the activation of SMA (under elevated temperature) fibres. Finally, the influences of all different structural design (aspect ratio, thickness ratio, boundary conditions, load intensities and crack dimension), material (SMA relevant data), environment and damage effects on the static flexural deflections are examined through a series of examples.
