While the cross-sectional area of individual elements 70 may be varied within the scope of the present invention, the shear modulus G eff behavior can be divided into primarily two categories from the standpoint of standard beam theory: "fixed-free" and "fixed- fixed.” Each category will now be described.

  • "fixed-free” refers to a beam model where only one end of the beam can transmit a bending moment. More specifically, posts or columnar elements 270 are fixed at end 290 to an inner extensible member 260. At the other end 280, columnar elements 270 are free or pivotable at the point of connection 300 to outer member 250. As shown in phantom in Fig. 2, when a force F is applied to shear band 240 as shown, columnar elements 270 experience a bending moment along ends 290 while ends 280 do not experience a reactionary moment. Assuming that the deflection v is small relative to the height h (along the radial direction R) of columnar elements 270, the strain experienced by post 270 becomes
  • deflection v can be calculated as follows:
  • Ge ff (3 * E * I * n)/(h 2 * A) where A is the total area normal to the beams.
  • Fig. 3 schematically illustrates the fixed-fixed condition for post or columnar element 370.
  • "fixed-fixed” refers to a beam model where both ends of the beam can transmit a bending moment. More specifically, columnar elements 370 are fixed at both ends 380 and 390 to an outer and inner extensible member 350 and 360, respectively. As shown in phantom in Fig. 3, when a force F is applied to shear band 340 as shown, columnar elements 370 experience a bending moment along both ends 380 and 390.
  • Ge ff (12 * E * I * n)/(h 2 * A)
  • the fixed-free columnar elements 270 reduce Ge ff by a factor of 4 and necessarily concentrate the bending stress from force F at a fixed point.
  • the fixed-fixed columnar element 370 distribute the bending stress from force F to both ends of columnar elements 370. This reduces the maximum moment by half and increases the stiffness of columnar elements 370 so as to increase G e ff and the contact pressure P e ff.
