Experimental Investigation of Dynamic properties of AerMet 100 Steel

摘要：

　　The dynamic properties characterization of AerMet 100 Steel at four different strain rates,namely 560/s、1200/s、2500/s and 4200/s were carried by a SHPB system.The stress-strain curves at these strain rates are obtained and they were compared with the quasi-static test results to analyze its strain effects.By comparing the stress-strain curves under different strain rates and quasi-static results,it can be found that the AerMet 100 shows strong strain rate sensitivity.For example,its yield stress under quasi-static compression is 1800MP while the yield stress is around 2300MP under strain rate 4200/s with an incensement of 24%.The hardening modulus under static compression is larger than that under dynamic compression due to the softening by the high temperature during high velocity impacting.
