Abstract Metal foams are materials of recent development and application that show interesting combinations physical mechanical properties. Many applications envisaged for such materials, particularly in equipments passive safety, because their high capacity energy absorption under impact conditions. The damage analysis metallic is a complex problem must be performed finite strain context. Considering compression the dominant loading situations, deformation simulation including effects test...
Abstract One way to obtain a cellular metal with uniform microstructure is employ hollow metallic spheres welded or bonded. Such materials are known as MHSS (Metallic Hollow Sphere Structures). Cellular metals can be applied crash absorbers that act in compression and severely deformed. Thus, finite deformations damage must considered the numerical simulation. In this work, simulation via elements employed study mechanical behaviour of MHSS. The employs concept RVE (Representative Volume...
This work applies Gurson model to the simulation of damage in metallic foams. In first part, two approaches for application, i.e., hypoelastic and hyperelastic formulations are compared. Then, a study on minimum number cells be employed an experimental test adequately simulate behavior cellular material tension is presented. Finally, considering that compression dominant loading impact situations, including effects metal sample shown compared with results.
Abstract Metallic foams provide low density, high specific stiffness, energy absorption and good damping are thus interesting alternatives for structural applications. The impact is dissipated through cell bending, buckling or fracture. On the other hand, results of strain‐rate inertia effects during dynamic deformation cellular metals apparently conflicting. A deeper understanding found in studies that show relative importance depends on velocity geometry structure, but still no particular...
A general boundary element formulation for the stress analysis of bodies with ageing viscoelastic constitutive relations such as concrete or biological materials is presented. It shown that in case a constant Poisson modulus, domain integral vanishes. Otherwise, integrals are taken to by means dual reciprocity method. Computational details and examples given.
