DESCRIPTION:The Taylor test is a means to validate constitutive models at 
 high strain rates as well as a means to evaluate dynamic compression failu
 re properties of materials. Taylor testing has been intensively used in it
 s original configuration consisting of one cylindrical specimen impacting 
 an anvil made of hard steel to reproduce a rigid wall and referred as the 
 classical Taylor test. With the use of symmetric impact\, the rigid wall a
 ssumption and guessing the friction coefficient are no longer needed to si
 mulate the Taylor test.\nSymmetric loading procedures for high strength an
 d low strength metallic materials will be presented along with comparisons
  between classical Taylor and symmetric Taylor experimental and numerical 
 data. The use of the symmetric Taylor test so as to characterize failure m
 echanisms involving adiabatic shear banding in metals will be also discuss
