The distributed forces are given by the following equation:

 

                                                 

which can be detailed for a constant thickness n-noded izoparametric finite element as:

 

                               

where Qx and Qy are the components of distributed load along the x and y axis, and because the thickness of the finite element is constant (h=const) we obtain:
