Review of the Wave propagation
Where are the wave propagation problems useful? How does a dynamic equilibrium different from that of static equilibrium? What is low impact, high impact and ballistic impact? What is the effect of such loading rate on both equilibrium equations and materials?
What is the shape of longitudinal and transverse waves? What is the difference between wave propagation direction and particle displacement direction?
How do you generic form of wave propagation equation for both the cases in terms of displacements and wave velocity?
How do you compute strain, check for equilibrium and then establish the relations between problem constants, material constants and wave velocity?
Given the displacement field can you find out the type of wave, strain and wave velocity by applying all the field equations?
