Abstract We present an alternative topology optimization formulation capable of handling the presence stress constraints in a straightforward fashion. The main idea is to adopt mixed finite‐element discretization scheme wherein not only displacements (as usual) but also stresses are variables entering formulation. By doing so, any constraint may be handled within procedure without resorting post‐processing operation typical displacement‐based techniques that cause loss accuracy computation...
Abstract Current manufacturing techniques in the construction sector are slow, expensive and constrained terms of architectural shapes. In other sectors (such as automotive aerospace) use automated systems significantly improved safety, speed, quality complexity products. To realize real-scale structural elements for applications without ideally any geometrical constraints either size or shape, most suitable solution metallic is a directed energy deposition (DED) process referred to...
Within the context of lower bound theorem classical limit analysis, collapse stone masonry arches and domes characterized by finite friction uncertain compressive strength is addressed. Self-weight considered, along with a live point load applied at crown. A multi-constrained funicular approach based on concept force densities implemented to provide maximum static multiplier for any assigned value coefficient strength. The numerical method, which takes into full account stereotomy blocky...
The optimal design of composite structures made a solid phase and given fraction graded infill is addressed, using homogenization-based topology optimization accounting for uncertainty in loading amplitude. A two-phase material law with void implemented to control the amount be distributed, along its admissible density range. Numerical homogenization used derive macroscopic elastic properties an isotropic two orthotropic infills that are commonly additive manufacturing. minimum weight...
Abstract This study, framed within the context of lower bound theorem limit analysis, aims to assess anti-funicular equilibrium masonry arches and domes using a computational approach based on constrained force density method. In contrast commonly adopted classical Heyman’s assumptions, proposed here considers effects finite compressive strength in material. Assuming fixed plan projection for network with independent sets branches, suitable set local constraints is enforced at each joint...
The design of spatial truss networks for fabrication using Wire-and-Arc Additive Manufacturing (WAAM) is addressed, combining funicular analysis and optimization. At first, a characterization the structural behavior printed bars provided based on available experimental tests. Interpolation laws are given both yielding stress critical in compression, depending printing direction. Then, dealing with fixed plan projection, minimization problem formulated terms any independent subset force...
