Large Diameter Compression Split-Hopkinson Bar Apparatus

Some materials require large sample sizes to maintain their aggregate mechanical characteristics.  Examples of these materials include woven composites and concrete.  These sample sizes may be too large for the small diameter SHB apparatus to accomodate.  Because of this, the Dynamic Mechanics of Materials Laboratory has designed and constructed a large diameter compression SHB. The apparatus, see Figure 1, is comprised of 2 inch diameter Ti-6Al-4V bars.  Operation of this device is identical to that of the small diameter compression SHB.
