While an array of strain gauges gives a series of point strains that can be used to validate a numerical model and to establish the biaxial strain field in the test region, this technique has ...

Compact in size, the RF9 strain gauge rosette features a three stacked measurement grid that is only 5mm in size, enabling it to determine a biaxial stress state with unknown principal stress ...

On the basis of the band-piezoelectric effect, a graphene nanogenerator and a pressure gauge ... via strain engineering. In this article, a unique 2D piezoelectric effect on a biaxial-strained ...

The Bucknell University planar biaxial testing system ... sole points or set multiple virtual extensometers and non-contacting video-based strain data has adjustable gauge lengths and extension ranges ...
