Replying to Do edge cracks ever occur because of tension from the ski flexing?

Only the thin middle layer of a ski is going to not feel tension/compression when the ski bends/flexes. The edges on the bottom are going to experience compression when the tip and tail of the ski flex downwards, but more importantly the edges will experience tension when the tip and tail are flexed upwards. Can this tension snap the edge and cause an edge crack? How do ski makers build skis so that the different layers are elastic/flexible enough to deal with differential amounts of stretching/compressing from the base to the topsheet? Are the glues they use elastic?
