IMPACT STRESS WAVE PROPAGATION IN A COMPRESSOR VALVE.

Author(s) : KIM J. S., SOEDEL W.

Summary

THE PAPER IS AIMED AT THE FUNDAMENTAL UNDERSTANDING OF THE IMPACT FAILURE MECHANISM OF THE VALVE PLATE. THE ANALYTICAL SOLUTION OF THE DISPLACEMENTS OF THE HALF-SPACE DUE TO A POINT IMPACT LOAD AS A GREEN'S FUNCTION IS DERIVED. THE NUMERICAL SOLUTION OF THE DISPLACEMENTS AND STRESSES IN A PLATE DUE TO THE AXISYMMETRIC IMPACT PRESSURE ARE OBTAINED AFTER APPLYING THE SPECIAL CONVOLUTION AND SUPERPOSITION ALGORITHM DEVELOPED BY USING THE HALF-SPACE SOLUTION. THE WAVE EFFECT ON THE MATERIAL FAILURE IS CLEARLY DEMONSTRATED.
