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

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 ...

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 ...

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 ...

Agarose hydrogels are rapidly becoming a popular option for an implantable scaffold material due to their biocompatibility, native tissue-like viscoelastic mechanical properties and ease of casting ...

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 ...
