4. Modelling "rigid" shocks

4.1 Wave propagation in materials

When two solids collide, a compression wave is generated on either side of the impact zone. In the case of uniaxial propagation, the celerity of the elastic wave in a material is expressed according to the following relationship:

c=Eρ( 16 )

with :

E
 : 
(Pa) Young's modulus of the material,
ρ
