A Review on Magnetorheological Fluids and its Stabilization Techniques
Abstract: AbstractMagnetorheological fluids are fluids which can alter its physical and rheological properties in response to an external magnetic field. They find many applications in shock absorbers, semi-active dampers, clutches, brakes, haptic actuators and devices. The rheological properties of these fluids can be altered using additives in the fluid composition and hence, the limitations due to settling tendency can be reduced to an extent. Hence, a detailed study on stabilization of …

Numerical Modeling of Elastoviscoplastic Material Model in Strain Space
Abstract: Conventional material non-linear analysis works with stress-space plasticity. It uses yield function, loading-unloading criteria, and flow rule in terms of stress parameters. It shows ambiguity in loading-unloading criteria for softening materials. During such situations, an alternative strain-space formulation becomes quite useful to carry out analysis of such materials. The viscoplastic response of materials requires the time integration of system of non-linear first order differential equations. In viscoplasiticy, the constitutive equation …
