“…The experimental report has furnished the relevant parameters of the material constituting the beam and the limit bending moment has been calculated considering the experimental results. It has to be considered that some buckling of the cross section of the beam occurs, the effects have been neglected in present work, although they could be considered [20,21]. The same structure has been analysed by means of the Melan's theorem accordingly to the proposed procedure.…”

Safety assessment of structures can be obtained by means of limit design in order to overcome uncertainties concerning actual response due to inelastic constitutive behaviour and more generally to non-linear structural response and loads’ random variability. The limit analysis is used for evaluating the safety of the structures directly starting from load level without any knowledge of the load history. In the paper, the lower bound calculation is proposed based on permanent strain parametric description of the residual stress. The strategy allows considering the permanent strain as the effective parameters of the procedure and can be used to control the ductility requirements until complete load program develops. In this way one can control if the structure can develop entirely its possibility of plastic adaptation up to required load level. The procedure is compared to experimental results obtained on aluminium beams in shake down.

“…Typical failure mechanism in this stage are related to lateral-torsional buckling. Recent works on the buckling behaviour of isotropic plates have been carried out taking into account the effect of transverse shear deformation [5]. 3) Manufacturability: the CFP has to be produced by a standard rolling process with low residual stress and without any additional process for improving bonding.…”

A new steel-concrete composite system is herein proposed to achieve a stronger, more ductile, and more economical flooring solution. The system consists of a smooth cold-formed steel profile fully embedded into a concrete pouring; Expanded Polystyrene (EPS) or hollow blocks are interposed between the steel profiles in order to lighten the slab weight. The system relies on particular shape and web holes only to achieve vertical interlocking and bonding resistance between concrete and cold-formed profile. The profile's shape has been properly designed through a multi-objective optimization process considering flexural performance, selfsupporting capacity, manufacturability, ease of installation, and compatibility with existing technologies. An experimental testing campaign on full-scale specimens has been carried out to investigate the flexural capacity of the system up to failure.

“…However, ceramics, in contrast to metals, have a fragile nature so crack-like defects are usually induced under service load conditions. From the above statement, FGMs are widely used in the research and manufacturing industry to optimize and design [7,8,9].…”

The paper describes the Field Boundary Element Method applied to the fracture analysis of a 2D rectangular plate made of Functionally Graded Material to calculate Mode I Stress Intensity Factor. The object of the Field Boundary Element Method is the transversely isotropic plane plate. Its material presents an exponential variation of the elasticity tensor depending on a scalar function of position, i.e., the elastic tensor results from multiplying a scalar function by a constant taken as a reference. Several examples using a parametric representation of the structural response show the suitability of the method that constitutes a sight of Stress Intensity Factor evaluation of Functionally Graded Materials plane plates even in the case of more complex geometries.
