Abstract:
The fabrication and testing of a series of small scale The fabrication and testing of a series of small scale elastic models are presented along with a discussion of the elastic models are presented along with a discussion of the relative merits of the various techniques used. An acrylic relative merits of the various techniques used. An acrylic plastic folded plate and a filled epoxy hyperboloid of revo- plastic folded plate and a filled epoxy hyperboloid of revo-lution were instrumented with small strain gages while a flat lution were instrumented with small strain gages while a flat plate and a cylindrical barrel shell of clear epoxy were plate and a cylindrical barrel shell of clear epoxy were analyzed by three dimensional photoelasticity. Using the analyzed by three dimensional photoelasticity. Using the stress freezing method, these epoxy models were sliced and stress freezing method, these epoxy models were sliced and the bending -and in-plane . the bending and in-plane stresses were directly obtained stresses were directly obtained from photoelastic readings. from photoelastic readings.
