Abstract:
1. A shear band defining a radial direction, the shear band comprising: a composite shear layer having an overall dynamic shear modulus, said composite shear layer comprising at least (i) one or more layers having a first dynamic shear modulus and a first total volume fraction, (ii) one or more layers having a second dynamic shear modulus and a second total volume fraction, wherein the ratio of the second dynamic shear modulus to the first dynamic shear modulus is at least about 3, and wherein said one or more layers having a first or second dynamic shear modulus are arranged in an alternating manner between layers having the first dynamic shear modulus and layers having the second dynamic shear modulus; at least a first membrane adhered to a radially inward extent of said composite shear layer; and at least a second membrane adhered to a radially outward extent of said composite shear layer; wherein a ratio of the longitudinal tensile modulus of one of said membranes to the overall dynamic shear modulus of said composite shear layer is at least about 100:1.
