The influences of damage and damage evolution on the nonlinear dynamic response and dynamic buckling for thin shallow spherical shells with circular hole are investigated.

If the shear lag is too large, should take appropriate measures to prevent such stress concentration phenomena, and to prevent cracking or buckling due to local production caused structural damage.

In order to prevent the glass fibers of the glass-polypropylene hybrid yarn from damage, the buckling of the crosslinks has to be avoided.
