Planar Biaxial | Biaxial Testing Systems
Constitutive models are necessary to predict the mechanical behavior of biological tissues. However, biological materials present challenges in constitutive modeling due to their complex mechanical behavior. Their oriented fibrous structures often exhibit pronounced mechanical anisotropy. Due to anisotropy, stress-strain data generated from uniaxial tests cannot be used to extrapolate to generalized three-dimensional constitutive equations. Since biological tissues are generally considered incompressible, planar biaxial testing allows for a two-dimensional stress state that can be used to characterize their mechanical properties and validate the constitutive models.
ADMET planar biaxial testing systems are engineered solutions based on specimen sizes, specimen elongations, test speeds, force capacities, environmental conditions, and gripping requirements. Each system comes equipped with ADMET’s biaxial version of the MTESTQuattro Materials Testing System capable of force, displacement, strain control (using DIC system) in addition to sine, square, triangular cyclic waveforms, and independent or synchronized control of X & Y actuators.
