Accuracy and stability of two-dimensional bilinear four-node and serendipity eight-node ﬁnite elements was tested in a wave propagation simulation. The inﬂuence of different parameters such as the element type and size, the value of mass lumping parameter, and time integration step was investigated. The outcome of the theoretical dispersion study was veriﬁed by numerical and analytical solutions to the longitudinal impact of two thick plates. ´
