A TECHNIQUE FOR THE CALCULATION OF ACCELERATION WAVES IN NONLINEAR VISCOELASTIC MATERIALS.
CALIFORNIA UNIV BERKELEY STRUCTURAL ENGINEERING LAB
A boundary-value problem giving rise to a one-dimensional acceleration wave in a nonlinear viscoelastic material is shown to have a solution, valid in a region behind the wave front, such that stress, strain and velocity are expressed as power series in time measured from the arrival of the wave the coefficients are functions of position and obtainable by quadrature from first-order differential equations. The results may be used to determine short-time viscoelastic behavior by means of wave-propagation experiments.
