Dummy unit load method and virtual work method are two different approaches.
State whether the above statement is true or false.
Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection
To apply this method it is :-
Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection
This method can be applied when:-
Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection
This method can be applied when:-
Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection

Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection
What is the shape of load-deformation curve for a non-linear elastic member?
Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection
What is the relation between work done and complementary work done?
Ue = work done by all external forces
Ui = internal work or strain energy
Δ = final elongation of bar
Θ = final angular deflection
