Searching light construction capable of carrying concentrated mechanical static load was the fundamental target of undertaken problem. There were presented the numerical simulation results of 3D skeleton casting with regular built of elementary cell. The simulations were realized using CATIA software with use of Advanced Meshing Tools module. As a skeleton’s material near-eutectic aluminum silicate alloy AlSi11 was used. The aim of the study was verification of the suitability of the regular geometry of elementary cells carrying mechanical loads (including stress) and deformation analysis of the model skeleton casting. The skeleton was tested for characteristic cell size of 20 mm and connectors diameter forming elementary cells equal to 6 mm. The value and the accumulation of localized regions of stress were shown that allows the precise modification of the skeleton macrostructure.Keywords: Skeleton casting, stress, relocation, numerical simulation, optimization.
