$ Kevlar Material Parameter Set
$
$ Description:    Kevlar is a ballistic fabric with exceptionally high resistance
$                 to perforation. Due to its lightweight and mechanical 
$                 properties, it is ideal for use as a jet engine containment  
$                 material. Often several layers of fabric are used to offer
$                 adequate protection to perforation from projectiles. 
$                 The material model developed by Arizona State University (ASU) 
$                 has the capability of modeling multiple layers of Kevlar fabric
$                 using multiple fabric plies in a single shell element. 
$                 The advantage of this approach is reduced computational time 
$                 due to fewer element and contact calculations.

$ Units:     There are two data sets using different unit systems that are 
$            referenced in the Test Case Suite both of which are included here:
$    Test Case 2.2:  in (length), s (time), lbf (force), 
$                    lbf-s^2/in (mass), psi (stress), lbf-in (energy)
$    Test Case 4: in (length), ms (time), Mlbf (force), 
$                 Mlbf-ms^2/in (mass), Mpsi (stress), Mlbf-in (energy)
