In this paper, the nonlinear mechanical response of elastic cable structures under mechanical load is studied based on the discrete catenary theory. A cable net is discretized into multiple nodes and edges in our numerical approach, which is followed

The mechanical behavior of aluminum honeycombs subjected to quasi-static combined compression-shear loading was experimentally investigated. Two different deformation patterns were observed, deforming cell walls non-inclined (Mode I) and inclined (Mo

In aerospace engineering, structural modifications play an essential role in design of structures. In some cases, it is necessary to guarantee that a specific natural frequency of the structure remains unchanged when additional masses are attached. T

Design optimization of dynamic properties, for example, modal frequencies, can be of much importance when structures are exposed to the shock and/or vibration environments. A modal strain based method is proposed for fast design of natural frequencie

The design of stiffeners is an effective approach to enhance the stiffness of panel-type structures. However, the stiffness–mass efficiency depends largely on the spacing, orientation, and cross-section of the stiffeners. In order to improve the st
