thanks Mapes. sorry about the poor wording. basically, I need to estimate the bullet terminal velocity from the fracture energy of tempered glass when it breaks. E = 0.5mv^2, I know the mass of bullet. I can estimate the velocity when I know the energy right? for example, to penetrate...

hi, I have a question about this relation btw Stress/Energy. if I know the failure stress/fracture of tempered glass, (~17000 psi = 117 MPa), how do I relate that to fracture energy of that glass? or are they completely different things? Energy = J = Nm Stress = N/m^2 need a volume...
