Shear Crimping

AID Analysis Name
105 Shear Crimping, X & Y Interaction (Hexcel)
106 Shear Crimping, Min Principal Stress (Hexcel)

Shear crimping is a general panel instability failure mode which manifests as a short wavelength buckle. This failure is caused by the low shear modulus of the sandwich core. The shear crimping allowable force is a function of the core depth (tcore), the shear stiffness in the direction of loading, and the facesheet thickness.
