Hi,

The lamb wave on solid has 2 modes Extensional (S0) mode and Flexural (A0) mode.

I have found a paper that has closed form solution for the Flexure mode of a Plate subjected to point impact load.Article Transient bending waves in plates studied by hologram interferometry

But, I am looking for a closed form solution for Extensional mode of a Plate of such loading condition. The solution in terms of displacement is better.

Do you know any paper or document which have this?

The Image attached shows the stress wave generated due to impact.

Thanks.
