Viscoelasticity print that page

Elastic_v._viscoelastic_2

researched and experimented with creep and recovery of glasses , metals , and rubbers . [ 2 ] Viscoelasticity was further examined in the late twentieth century when synthetic polymers were engineered and used in a variety of applications. [ 2 ] Viscoelasticity calculations depend heavily

Mohr-Coulomb theory print that page

In Geotechnical Engineering it is used to define shear strength of soils and rocks at different effective stresses . In structural engineering it is used to determine failure load as well as the angle of fracture of a displacement fracture in concrete and similar materials. Coulomb 's friction

Standard Linear Solid model print that page

The standard linear solid (SLS) model , also known as the Zener model , is a method of modeling the behavior of a viscoelastic material using a linear combination of springs and dashpots to represent elastic and viscous components, respectively. Often more similar Maxwell model and the Kelvin

Rheometer print that page

Rheometer

A rheometer is a laboratory device used to measure the way in which a liquid, suspension or slurry flows in response to applied forces. It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the

elements. Rate-dependence can be represented by nonlinear dashpot elements in a manner similar to viscoelasticity . Plasticity can be accounted for by adding sliding frictional elements as shown in Figure 1. [ 2 ] In the figure E is the modulus of elasticity , λ is the viscosity parameter

Quartz crystal microbalance print that page

Quartz_resonators_with_front_and_back_electrodes

A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film deposition at the surface of the acoustic resonator
