Loss Modulus

In addition to the fairly large transitions shown up by large peaks in the loss modulus, there may be minor transitions, causing small peaks or shoulders.These may be due to other deformation mechanisms, though Moseley [23] attributed a large collection of small peaks at large strain amplitudes to non-linearity of response, and Dumbleton and Murayama [24] …

What does an increase in loss modulus but no change in storage modulus mean …

I''d like to find out thoughts on what it means for a hydrogel in terms of structural properties, strength, etc when there is no change in the storage modulus after adding a drug but ...

Passive myocardial mechanical properties: meaning, …

The storage modulus quantifies the ability of a material to store energy elastically, while the loss modulus describes its ability to dissipate energy. Materials with a large storage modulus are generally regarded as elastic, whereas those with a large loss modulus are generally considered viscous (Fig. (Fig.2c, 2c, Patra et al. 2020 ).

Young''s modulus | Description, Example, & Facts | Britannica

Young''s modulus = stress/strain = ( FL0 )/ A ( Ln − L0 ). This is a specific form of Hooke''s law of elasticity. The units of Young''s modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m 2 ). The value of Young''s modulus for aluminum is about 1.0 × 10 7 psi, or 7.0 × ...
