Further information on the model
I am using Linear solid elements C3D8 and C3D6. The model contains a composite plate joint to an aluminium plate with a titanium countersunk bolt. I have modeled all the components of the joint using solid elements. I have also implemented contact and friction in the model. the joint is fixed at one end and loaded in tension on the other end.
Your help will be much appreciated.

I am aware of the fact that FEM models are usually stiffer than the real structure, however my model is too stiff compared to the real structure.

I would like anyone to suggest ways to reduce the stiffness of the model. Please give ideas, how can I reduce the stiffness of the model. Thanking you in advance.
