Fig. 3 from the 1997 modejump paper. This slide is a schematic showing the types of branching and initial conditions that can be handled by STAGS for mode jumping. (drawing by Eduard Riks)
Mu is the buckling modal amplitude in the perfect plate or shell, and lambda is the applied load. (NOTE: the label "1" in (A) should be "2": a second equilibrium path of the perfect plate or shell.)
