  4. Abstract:
  5. Real loading- unloading behavior of an A5083 aluminum alloy was recorded experimentally. This real behavior was incorporated in the variable material properties (VMP) numerical algorithm to predict residual stresses resulted from autofrettage and shrink fit in two kinds of autofrettage compound tubes. Using an analytical method, residual stresses induced by bore material removal via machining were calculated. Using developed VMP code and isotropic hardening rule in both autofrettage compound tubes, residual stresses resulted from shrink fit and autofrettage processes and via post machining, were estimated. Machining process simulation was performed for 10 mm bore material removal. ANSYS commercial FEM software was used for validating the results of VMP code. The results of VMP method and ANSYS were in good agreement with each other. Finally with the help of recorded real unloading behavior of A5083 aluminum alloy, also aforementioned simulations were performed on various tubes. The material removal simulation was modeled for 5 mm to 15 mm material removal from the bore. Copyright © 2007 by ASME
