The finite element analysis of dynamic problems in an infinite, isotropic medium is discussed. To simulate the physically infinite system by a finite model, an energy absorbing boundary is proposed. This boundary is frequency independent and proves to be very efficient in absorbing stress waves. The boundary constants are calculated for the particular cases of plane strain and axisymetry. /Author/TRRL/
