Abstract

An axisymmetric finite element model of the pusher plate, blood sac and pump case was constructed to assess whether stresses in blood sacs were due to high tensile forces on the outer surface in the region of maximum bending of the sac. When the taper was removed from the pump case, the maximum Von Mises stresses in the 0.015 thick sac decreased from 227 to 150 psi, and reduced the strain from 0.21 to 0.13.
