Theoretical analysis of tensile stresses and displacement in orthotropic circular column under diametrical compression
Takashi Tsutsumi, Hiroshi Iwashita and Kagenobu Miyahara

 
Abstract     [Buy Article]
    This paper shows the solution for an orthotropic disk under the plane strain condition obtained with complex stress functions. These stress functions were induced by Lekhnitskii and expanded by one of the authors. Regarding diametrical compression test, the finite element method poses difficulties in representing the concentrated force because the specimens must be divided into finite elements during calculation. On the other hand, the method shown in this study can exactly represent this force. Some numerical results are shown and compared with those obtained under the plane stress condition for both stress and displacement. This comparison shows that the differences between the tensile stresses occurred under the plane strain condition and also that the differences under a plane stress condition increase as the orthotropy ratio increases for some cases.
 
Key Words
    orthotropy; diametrical compression; tensile stress; displacement; plane strain condition.
