Numerical modeling of honeycomb structures in aerospace engineering is too tedious and time consuming. The homogenization of these structures permits to obtain an equivalent orthotropic homogeneous solid and its elastic effective properties and thus

This paper presents some general two- and three-dimensional finite element models to study the equivalent orthotropic mechanical properties of honeycombs. The models are developed on a representative volume element with appropriate periodic boundary

The measurement of steady and fluctuating forces acting on a body in a flow is one of themain tasks in wind-tunnel experiments. Usually, a multi-component strain gauge force and momentsensor (also known as balance) is used to generate signals which a

In the present paper the hexagonal honeycombs with double vertical walls (commercial), which usually are used as cores in sandwich plates, and the rigid skin effect are considered. Loaded in out-of-plane shear, the core is designed to have an identic

In the present paper a general parameterization of a periodic hexagonal honeycomb with double vertical walls (commercial honeycomb) is proposed and a new analytic model is established. More attention is paid to account for the radius of curvature of

In the present paper the skin effect is neglected, and a general parameterization of a hexagonal honeycomb, valid for constant wall thickness, double vertical walls (commercial), or for any combination of cell walls is generated. Thus, two new analyt
