Lamb's problem is related to wave propagation in a semi-infinite elastic medium subjected to an impulsive force applied at the surface, Lamb (1904). The problem is simulated in PLAXIS and the results are verified against Lamb's solution, which has been considered by, among others, Miklowitz (1978), Cagniard, Flinn & Dix (1962) and Foinquinos & Roesset (2000). In the present validation, the closed form solution introduced by Foinquinos & Roesset (2000) is adopted as reference.
In this validation, comparison is made between PLAXIS results and results obtained from the closed form solution introduced by Foinquinos & Roesset (2000) for solving Lamb's far field problem.
This requires the Dynamics module.
