Shear Properties

Shear properties describe how materials respond to forces that cause layers within them to slide relative to one another. These properties are critical in industries like pharmaceuticals, food, and construction, where understanding material flow, stability, and strength is essential for efficient processing and reliable product performance.

On this page, explore the principles of shear properties, methods for their measurement, and their applications in optimizing material handling and processing.

    Angle of Repose Is Not a Flowability Test

    The angle of repose and flowability are related, not equal. Use the angle as a quick screen, then decide with density, timed discharge, shear, and wall friction data. The angle of repose and flowability feel linked because a cone seems intuitive. However, small method changes shift the result [...]

    Deep-Sea Particle Dynamics, Through a Powder Lens

    vDeep-sea particle dynamics show powder engineering mechanics in powder dynamics. Deep trenches act as natural particle processors. Marine snow, fecal pellets, and mineral dust form fast-sinking aggregates that carry microplastics and fines to the seafloor. The same physics governs industrial powders. Shape, density contrast, aggregation, and turbulence set fate and wear. Engineers can [...]

    Shear cell testing is the most effective method for predicting and controlling powder flow. It transforms complex, unpredictable behavior into measurable parameters that prevent clogs, improve consistency, and support safe, efficient processing. Table of Contents Powders fool people. At first glance, they look dry, clean, [...]

    Selecting the Right Powder Mixer for your blend

    There is no one-size-fits-all powder mixer—the right choice depends entirely on your powder’s flowability, sensitivity, particle size, and process needs. Whether you need gentle handling for fragile particles or intense shear for cohesive blends, matching the mixer to your material ensures better blend quality, efficiency, and product consistency. Selecting the wrong mixer can [...]
