“…These SCM can be used as two phase material [36], reinforcing elements for cement composites with fractal architecture [37], shape optimization of the force networks of masonry structures for civil engineering applications, tensegrity architecture, meta-material printing [38][39][40]. The proposed route for recycling of plastic solid waste is in line with the application domain discussed by other investigators via 3D printing [41][42][43][44][45][46].…”

In the present work, a sacrificial patterns (SP) for investment casting (IC) were prepared with three dimensional (3D) printing (by using fused deposition modelling (FDM) setup) from recycled high density polyethylene (HDPE) recovered from domestic waste reinforced with Al 2 O 3 and SiC particles in different proportions. These SP were further used for preparation of sandwich composite material (SCM) as a novel process. Finally casted functional prototypes as SCM were investigated for surface hardness, porosity and grain size measurement supported by photomicrographs and scanning electron microscope (SEM), energy dispersive x-ray analysis (EDAX). The results of the study suggest that SCM prepared by proposed route have acceptable hardness (34.9 HV) and porosity (6.16%) for Polypropylene PP RECEIVED

“…Within this framework, [40] focuses on computational aspects, offering iterative procedures for both vertical and horizontal loads. Other static methods model masonry vaults as notension membranes [26,28,52] or derive truss-like stress paths from Airy stress functions [9,10,27,31,43], using mathematical tools for approximating stress in continuous bodies through discrete force networks.…”

This study, framed within the context of the lower bound theorem of limit analysis, aims to assess the anti-funicular equilibrium of masonry arches and domes using a computational approach based on the constrained force density method. In contrast to the commonly adopted classical Heyman’s assumptions, the approach proposed here considers the effects of finite compressive strength in the material. Assuming a fixed plan projection for a network with independent sets of branches, a suitable set of local constraints is enforced at each joint to account for the limit bending moment resulting from the material’s assumptions, including limited compressive strength and zero tensile strength. Additionally, the stereotomy of the voussoirs is considered by assigning a geometric law to the joint inclination. The collapse load is determined by formulating a multi-constrained maximization problem. The method is validated using a modern version of the semi-analytical Durand-Claye’s method. For benchmark case studies, such as symmetric masonry arches and domes with specific stereotomies subjected to axi-symmetrical load conditions, the set of statically admissible solutions compatible with equilibrium and strength requirements is graphically determined in terms of the horizontal thrust and its eccentricity at the crown, examining the shape of the stability area. Assuming an infinite value for the friction coefficient, the collapse condition is reached when the stability area shrinks to a single point. The results obtained from both of these methods are in excellent agreement. The influence of compressive strength on the bearing capacity of the structures is also discussed.
