| Abstract: | The iterative algorithm and finite element model were built to investigate the deformation and stress of PMMA hollow transparency used in porthole according to the specific loading characteristics.The deformation obtained from proof tests and calculations were consistent with each other,which implied the accuracy of the algorithm and finite element model.Then the calculations were performed to deal with different pressure out of cabin,different thickness of PMMA panel,and different thickness of gas layer.Th... |
