Hi ;
I have to solve this equation and u'' and v'' are the second order derivatives of longitudinal and transverse displacements along X axial ;
u^^ nad v^^ are second order derivatives versus time ( I used ^ instead . )
-pAu^^ +EA(u'+1/2*(v')^2)'=-EAu''

You won't find analytical solutions. So use one of the many methods to find and characterize numerical solutions of PDEs. Which probably means you need to do a lot of reading, before your fingers ever write any code.
