Title:
Experimental and theoretical study of deformation of multilayer honeycomb panels during shear test
Keywords:
multilayered honeycomb panels, elastic and strength characteristics, finite element model
Abstracts:
The paper presents an experimental determination of effective shear modulus and strength limits during shear tests of flat multilayer honeycomb panels with thin carbon fiber sheaths and fiberglass tape filler. A statistically significant difference in the effective shear modules along and across the tape bonding planes in the cells of the honeycomb, their inverse correlation with the total height of the honeycomb filler, was revealed. The effective shear strength limits do not differ statistically and do not depend on the total height of the honeycomb. Numerical analysis of the factors influencing the underestimation of the calculated values of the effective shear modules is performed on finite element models.
