A problem of damage prediction in aircraft structure and its non-destructive evaluation is very important for aircraft structural health assessment. The low-velocity impact was simulated. For laminate usually it associated with delamination which effect to compressive strength of long fiber composite is very significant. This damage is internal and its non-destructive detection is important for system of aircraft structural health monitoring (SHM). The analysis of the features of direct impact of thin-walled laminate component of aircraft was performed by COMSOL Multiphysics software. Some regularities of ultrasonic guided wave propagation in composite sheet with different kinds of damage were investigated by the simulation and compared with the special test. New approach for detection of delamination in composite plate is developed.
