Abstract:

Ultimate biaxial stress results are compared with several failure theories for two high density graphites, a steatite, and a filled epoxy-resin. The maximum strain energy theory appeared best for correlating the results if a single theory is used for all stress states. Data given for born nitride and two grades of glass-cloth, reinforced epoxy resing are meager. All results are for tubular test specimens loaded at room temperature by means of internal fluid pressure and axial loads. Author
