SATOR is able to provide response to the most complex requirements of design by means of the technique of Finite Elements, also known by the acronym FEM (Finite Element Method - mainly devoted to the study of structural phenomena aimed at the evaluation of the stiffness, the strength and the elastic stability of bodies). With the experience gained over the years, we are able to perform structural analysis on aeronautical structures and mechanisms and complete machines. We also have experience on boats, cars, consumer goods and industrial plants.

SATOR, through the multi-body analysis, can simulate the kinematics, dynamic and structural mechanical assemblies with multiple parts in reciprocal motion between them (kinematics). With the experience gained over the years, we are able to perform multi-body analysis of complete machines and sub-groups.

In the area of Aerospace most of real structures are subject to vibrational fields. Application scenarios in which SATOR was committed are among the most extensive and range from vibrations induced by aerodynamic loads of Aeronautical Structures, vibrations from the engine and the taxiway on the aircraft structure, a complex vibrational situations such as those to which it is subject to the structure of a satellite and launcher. SATOR has all the technical knowledge for the assessment of the behavior of a mechanical system in vibration conditions can be simulated effectively starting from the calculation of the natural frequencies and mode shapes of their own, using structural dynamics simulations as FRF (Frequency Response Function), the shock and random analysis.

SATOR has developed multiple evaluation projects and their optimization in terms of durability of the Aeronautical / Mechanical components, performed with metallic materials (steel, aluminum alloys, titanium alloys), plastic materials and composite materials, loaded to fatigue uniaxial, biaxial, multiaxial, Low cycle, a high number of cycles (HCF Fatigue). Starting from the experimental data availability, type of material, SATOR use stress-life stress approaches (S-N) or strain-life (Ɛ-N), implemented in commercial calculation code such as Nastra Patran. Specific studies have been conducted on the fatigue strength of welded joints.

When a system is subjected to varying stress abruptly in time it is not possible to predict accurately the behavior using static analysis "equivalent": the transient dynamic simulation is nonlinear, the only way forward. With the experience gained over the years, SATOR is able to perform dynamic structural calculations of impact and crash, especially in the aerospace sector.
