Abstract
Knowledge of the transverse mechanical properties of honeycomb cores i s essential for the design of sandwich panels. This paper deals with t he calculation of the transverse shear moduli of a honeycomb sandwich panel by making a finite element study of a representative unit cell. Stress contours inside the honeycomb are also provided. Three cell geo metries are studied and the influence of the thickness on the shear mo dulus and on the homogeneity of the shear stress field is investigated .
