The paper presents results of numerical and experimental investigations of elastic wave propagation in a bolted single-lap joint. The research was carried out for both symmetric and antisymmetric Lamb wave modes. In experimental studies the PZT transducers were used to excite and register wave propagation signals. The controlled value of the torque during measurements was ensured by the use of high precision torque wrenches. Numerical model of the joint was developed by the finite element method using commercial software Abaqus. The analysis took into account varying contact conditions between the connected parts of the joint depending on the value of the bolt torque. Both experimental and numerical results showed the influence of the value of the pretension force on the amplitude and phase shifts of registered signals.
