WebThe simple constitutive relationship for a dashpot indicates that the force in the fluid depends on the rate the dashpot is displaced, or equivalently the velocity of the … WebThe value of 1 (10^6) Pa-s is used as the viscosity in the second term of the constitutive equation because it represents the resistance to flow of the Maxwell Fluid model. The viscosity is a measure of the material's resistance to deformation over time, and in this case, it is equal to the viscosity of the dashpot in the Maxwell Fluid model.
http://websites.umich.edu/~bme332/ch7consteqviscoelasticity/bme332consteqviscoelasticity.htm A dashpot, also known as a damper, is a mechanical device that resists motion via viscous friction. The resulting force is proportional to the velocity, but acts in the opposite direction, slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation … See more The two most common types of dashpots are linear and rotary. Linear damper Linear dashpots — or linear dampers — are used to exert a force opposite to a translation … See more Dashpots frequently use a one-way mechanical bypass to permit fast unrestricted motion in one direction and slow motion using the dashpot in the opposite direction.
