摘要：

We have made use of a previously ignored quantity, stick-slip friction, in determining powder flow properties. Stick-slip friction can easily be measured with a Table Model Instron or similar device. The stick-slip friction of most powders can be measured with greater accuracy and precision than any type of angle of repose measurements. Stick-slip friction values for a set of plastic powders were related to the particle size, flow properties and tensile strength. While stick-slip friction may not be universally relatable to flow behavior, it does hold promise for more limited sample tests. © 1979.
