For linear elastic materials (3D General)...

The virtual work equation looks exactly like the equation for potential energy except that in the potential energy equation, the internal work term has a (1/2) coefficient. Why are these different?

Do you know why the potential energy has a 1/2 coefficient?

It has to do with the method of application of the loads, which is different for VW.

That doesn't answer the question.

Equation of Virtual Work VS Potential Energy

Actually I did provide an answer, albeit very short.

But I still don't know if you understand where the 1/2 comes from.
