dc.description.abstractThe rate-dependence, recoverable and irrecoverable nonlinear deformation behavior of microhybrid and nanofilled dental resin composites cured with the conventional light emitting diode (LED) and exponential light emitting diode (HiLED) composites under uniaxial loading is here presented. Experimental study based on displacement controlled multiple stress creep recovery (MSCR) tests revealed hysteresis loop in loading and unloading states indicating an inherent viscoelastic nature, and at stress values less than 4 MPa, rate dependent recoverable strains were observed. But at stress values higher than 4 MPa, irreversible strains were observed which also indicates viscoplasticity. Hence a viscoelastic-viscoplastic constitutive model can be used to represent the material deformation behavior for the dental resin composite.en_US
