Hi,

I'm trying to solve for the modal transient dynamic response of a beam subjected to arbitrary loading in (time) and (measurement along the length of the beam). I've already solved for the eignefunctions that describe the beams displacement. I'm now trying to solve for the temporal solution. I get to

where is an arbitrary function determined from some integration and operation on the forcing fuction.

Question: Does anyone know how to obtain a solution to this equation for ? I'm not sure what to use as an initial solution guess.

Any help is much appreciated.

Thanks.
