5. TYPES OF PROBLEMS
Equilibrium problems
Time-independent problems in solid mechanics or steady-state problems in thermo-fluid mechanics.
Eigenvalue problems
Steady-state problems whose solutions often requires the determination of natural frequencies and modes of vibration in solids and fluids.
Problems involving the stability of structures and the stability of laminar flows.
Propagation problems
Time-dependent problems of continuum mechanics
