Abstract:
The equ iva lent elasticmodulus and the nom ina l ax ia l stress of non-regular holey lam ina-t ed plates are assumed. A plane stress mode l is presented in this paper based on the streng th theory of anisotropicmateria ls. Equ iva lent e lasticmodu lus and shear e last icmodulus and Po isson. s ra tio o f materia ls are obta ined through the experimen,t and themechan ica l properties and the fa ilure patterns are discussed for the corrugated paperboards and the po lycarbonate ho ley plates under the state o f plane stress. It is found tha t the stiffness rec iproca l re lationsh ip isw e ll satisf ied for each type o fm ateria ls. The experimental resu lts show that the mean tension strength of corrugated paper lam inated plates designed in 0 b- 90 b cross pattern is be tter than that designed in un iform ax ia l holes.
