The through-thickness stresses in thin shells are often assumed to be zero and this is normally justified by the fact that they are much lower than the in-plane stresses. However, if the shell is of laminated construction, the through-thickness strength can also be relatively low compared with the in-plane strength, so even small levels of tensile stress in the through-thickness direction can lead to damage by delamination. This paper first presents an equilibrium method of calculating the normal and shear components of these stresses for singly curved shells and rings of single- or double-skin construction. The formulae derived are then used to analyse a delamination test in the form of a split ring which is then used to determine the delamination strength of a number of filament wound tubes with various matrix compositions and lay-up geometries. As the changes in curvature can be large, the entire formulation is presented in terms of the current (deformed) coordinate system and the Cauchy stress.</p></div>","PeriodicalId":100296,"journal":{"name":"Composites","volume":"26 5","pages":"Pages 339-345"},"PeriodicalIF":0.0,"publicationDate":"1995-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0010-4361(06)80133-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84132035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the case of unidirectional laminates, brittle and toughened CF/epoxy, and CF/PEEK systems were used. Only a brittle CF/epoxy system was used for woven laminates. The round robin tests were conducted with two main aims: first, to examine the influence of starter films and the precracking condition on the initial mode I fracture toughness values; and second, to establish the definition of initial fracture toughness. Polyimide starter films stuck to the epoxy matrix, and caused unstable crack growth from starter films. Comparison of the tests with and without mode I precracks from starter films indicated that tests with precracks gave lower values of initial fracture toughness. The definition of initial fracture toughness values was discussed, based on the reproducibility. A 5% offset point was recommended as the initial fracture toughness from the RRT results. The influence of loading apparatus, data reduction methods, etc. was also discussed.</p></div>","PeriodicalId":100296,"journal":{"name":"Composites","volume":"26 4","pages":"Pages 243-255"},"PeriodicalIF":0.0,"publicationDate":"1995-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0010-4361(95)93668-A","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72548270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, the performance characteristics of the model are shown to be quite consistent with those of a concentric cylinder model formulation. Subsequently, a parametric study is performed that examines the mechanical response of model graphite/epoxy composites as a function of selected interphase properties. The micromechanical model is utilized to establish an interdependence among the interphase Young's modulus, the interphase thickness and the average stresses within the fibre, interphase and matrix resulting from two external loading conditions: uniaxial longitudinal tension and biaxial transverse shear. Material combinations are considered wherein the interphase Young's modulus is systematically varied above and below the matrix Young's modulus. The simulation indicates that the selected interphase properties significantly influence the stress state within each of the three composite constituents. The manner in which the stress states are modified proves to be non-intuitive in many of the cases considered. In particular, there are material domains encountered where the model predicts that certain stress components in a constituent will exhibit (1) a maximum with respect to variations in the interphase Young's modulus and/or (2) a minimum with respect to variations in the interphase thickness.</p></div>","PeriodicalId":100296,"journal":{"name":"Composites","volume":"26 4","pages":"Pages 269-280"},"PeriodicalIF":0.0,"publicationDate":"1995-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0010-4361(95)93670-F","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85637254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
