Constitutive Modelling of Polylactic Acid at Large Deformation Using Multiaxial Strains
Sheet specimens of a PLLA-based polymer have been extended at a temperature near to the glass transition in both uniaxial and planar tension, with stress relaxation observed for some time after reaching the final strain. Both axial and transverse stresses were recorded in the planar experiments. In...
