“…A table (T) is used to propagate four pulses to a brick with a Young's modulus of 15 GPa [24]. The brick (Sa) was placed over the table and all pulses were induced through the longitudinal direction (Lon) of the brick.…”

We present an optical experimental approach and an analytical model to calculate the strain on a brick when an external force-pulse is indirectly applied on its surface. We assumed that the displacement produced on the brick is energy that it transforms to deformation. To measure the displacement, we applied one laser-beam to the brick and took image data of the speckles created by its reflection. The speckles were processed using the digital image correlation technique and allowed us to evaluate the relative displacements caused on the surface of the brick. Then, based on the kinetic energy of forced and damped oscillations, we calculated analytical strain values of the order of ε ≈ 1.52×10-6 .
