In this work, important experimental controls for using indentation equipment to characterize viscoelastic solids in the frequency domain are presented along with a demonstration of the ability to ...

Typical nanomechanical applications include measuring elastic modulus, friction and adhesion. Viscoelastic materials, which include polymers and biological materials, have elastic properties that ...

Hysteresis is a measure of the amount of energy lost per cycle during deformation of an elastomer. Tangent delta, or the loss factor, is a measure of hysteresis and is the ratio of the loss modulus to ...

Pounding on the bottom of a glass bottle of ketchup is one of life's small annoyances. Getting that sweet, red concoction from its solid phase to a liquid takes too long when you're hungry and could ...

Quantitative characterization of nanomechanical properties has invariably been a holy grail for atomic force microscopy. This article explains some of the industry’s earlier attempts made at ...

O-rings of five different kinds were tested using the iNano indentation system from KLA. The data on each is displayed in Table 1. A flat cylindrical punch (D= 100 µm) was used to measure the complex ...

Polymers are often employed in engineering designs because of their ability to damp out shock and vibration. A material’s ability to elastically store energy is characterized by the storage modulus (E ...
