The dynamic compressive strength of ceramic armor materials is difficult to obtain experimentally due to the sensitivity of fracture strength to small misalignments, end effects, and surface effects. In this work we introduce a spherical joint into a

An inverse method is presented for estimating shear stress in the work material in the region of chip–tool contact along the rake face of the tool during orthogonal machining. The method is motivated by a model of heat generation in the chip, which

A special Kolsky bar apparatus with the capability to pulse heat the sample was built at the National Institute of Standards and Technology (NIST). This Kolsky bar laboratory’s initial purpose was to measure dynamic material properties in support o

Single PPTA [poly( p -phenylene terephthalamide)] fiber tensile tests using a Kolsky bar were carried out to investigate the effect of the strain rate on their tensile strengths. Since single fiber tests yield distributions of strengths, a large samp

Dynamic testing using tension Kolsky bars presents a number of challenges, including the design of the grips to hold the specimen. Basic solid mechanics suggests that a grip can be designed such that the lateral clamping-force times the coefficient o

The Pulse-Heated Kolsky Bar Laboratory at the National Institute of Standards and Technology (NIST) has been developed for the measurement of dynamic properties of metals. With this system, a small sample can be pre-heated from room temperature to se

A one-dimensional transient finite-difference model for the temperature distribution in orthogonal metal cutting, which was originally developed by Boothroyd, and then improved upon by Tlusty, is used to calculate the temperature field in the chip an

Frangible bullets are designed to disintegrate on impact against rigid surfaces to avoid ricochet hazards in recreational shooting ranges or law enforcement training facilities. Their impact behavior against protective soft body armor is therefore qu

The National Institute of Standards and Technology (NIST) has developed an electrical pulse-heated Kolsky Bar technique for measuring the constitutive response of metals at heating rates of up to 6,000 K/s and strain rates up to 104 s−1. Under thes

Analysis of machining processes is important in the understanding and improving of manufacturing methods. The modeling of machining processes relies on high-strain-rate, high-temperature material properties. A Split–Hopkinson (or Kolsky) bar has be
