ANALYSIS OF STRESSES AND DISPLACEMENTS IN THREE-LAYER VISCOELASTIC SYSTEMS

A SOLUTION TECHNIQUE IS PRESENTED FOR THE ANALYSIS OF THE STRESSES AND DISPLACEMENTS INDUCED IN A VISCOELASTIC THREE-LAYERED BODY SUBJECT TO BOUNDARY LOADS WITH DIFFERENT TIME CONFIGURATIONS. THE TECHNIQUE IS COMPOSED OF TWO PARTS: (1) THE USE OF A MODIFIED CORRESPONDENCE PRINCIPLE IN THE FORM OF HEREDITARY INTEGRALS TO CONVERT THE ELASTIC SOLUTION (TO A BOUNDARY VALUE PROBLEM WITH TIME-BOUNDARY CONDITIONS OF THE HEAVISIDE TYPE) TO THE VISCOELASTIC SOLUTION, AND (2) THE USE OF THE PRINCIPLES OF THE RESPONSE OF LINEAR SYSTEMS TO IMPOSED EXCITATIONS TO OBTAIN THE VISCOELASTIC SOLUTIONS TO BOUNDARY VALUE PROBLEMS WITH TIME-BOUNDARY CONDITIONS OTHER THAN THE HEAVISIDE TYPE. THE UNDERLYING PRINCIPLES ARE DISCUSSED, AND AN EXAMPLE OF THE USE OF THE METHOD IN THE ANALYSIS OF THE SRESSES AND DISPLACEMENTS INDUCED IN A THREE-LAYER VISCOELASTIC BODY SUBJECTED TO UNIFORMLY DISTRIBUTED NORMAL LOADS OF THE STATIONARY, REPEATED, AND MOVING TYPES IS PRESENTED. /AUTHOR/
