Kolsky Compression Bar Experiments at Intermediate Strain Rates
2010Most Kolsky bars characterize dynamic material properties at strain rates between 5×02 and 1×104 s-1. On the other hand, quasi-static material testing machines operate under closed-loop control at strain rates below 1 s-1. However, many applications require stress-strain data around the intermediate strain-rate range of 5×101 - 5×102 s-1, where data is

Journal of Polymer Science Part A-2: Polymer Physics, 1970
AbstractThe mechanical and optical properties of a polyester–styrene copolymer have been investigated by means of drop tests at strain rates from 38 to 113 sec−1 for strains less than 50%. Over this range of rates, the optical behavior was found to be linear with strain and independent of strain rate while the elastic–plastic mechanical behavior was ...

Tensile failure of austenitic iron at intermediate strain rates
Metallurgical Transactions A, 1975The basic failure behavior of austenitic iron has been established for the temperature range 950 to 1350°C and the strain-rate range 2.8 x 10-5 to 2.3 x 1(10-2 s-1. Failure in zone-refined iron is determined solely by plastic deformation, leading first to multiple necking, continuing by the exclusive growth of a single neck, and concluding by ...

A New Device for Tensile and Compressive Testing at Intermediate Strain Rates
Experimental Mechanics, 2019A new device for conducting tensile and compressive tests at strain rates ranging from about 20 s−1 to 250 s−1 is presented. The operation of the device is based on the principles of the Split Hopkinson Bar (SHB) technique, except that the incident bar is replaced by a fast hydraulic actuator and the transmitter bar is very long.

Intermediate and High Strain-Rate Testing of Soft Materials
AIP Conference Proceedings, 2006Strain‐gauged bars are often employed as load cells for direct impact testing of materials and are incorporated within the split Hopkinson pressure bar (SHPB). Low impedance bars (e.g., magnesium or polymer bars) are desirable when testing soft specimens such as various energetic materials and cellular solids. However, due to the rheological properties

Constitutive model of Q345 steel at different intermediate strain rates
International Journal of Steel Structures, 2017Structural elements of steel frame experience very high strain rates in the progressive collapse, and hence their constitutive properties do not remain constant but change significantly with time. Quasi-static and dynamic tensile tests of Q345 steel were performed to study the dynamic tensile behavior within the range of 0.001 to 330/s strain rates by ...

Plastic deformation of delta-ferritic iron at intermediate strain rates
Metallurgical Transactions A, 1976The plastic deformation of delta-ferritic iron, represented by an electrolytic iron and Fe-0.028 C, Fe-0.044 C and Fe-3.0 Si alloys, has been measured for the temperature range 1200 to 1525‡C and the strain rate range 2.8 x 10-5 to 2.3 x 10-2 s-1. For the bamboo-like tension specimens the plastic flow behavior is approximately nonlinear viscous.
