Abstract
The purpose of the recent project is giving empirical research of the dynamic properties along with measuring the damping ratio for different metal foam sandwich specimens, and mathematical modeling of these particular structures. Besides, the various specimens were modeled by employing ANSYS for the FEM analysis. Concerning to have a reliable result for two-phase sample the random noise outcomes have been applied and associated with the FE model. The final results depict an appropriate evaluation of the vibrational damping for two-phase specimens.
Highlights
Steel foams are defectively characterized, these materials have been developed instantly and are using as a new porous metal since the last decades [1]
The inspiration for this research project was based on the theory that the steel foams are an excellent class of composite materials that can be employed as the ultra-light stiffeners against buckling, which can mitigate vibrations in aerospace and civil applications, and some infrastructures such as wind turbine towers and steel bridges and armors either military or civil uses [2,3,4,5,6]
For the aim of reproducing of the damping behavior of steel foams in finite element analysis, the model is built in APDL ANSYS V19.1
Summary
Steel foams are defectively characterized, these materials have been developed instantly and are using as a new porous metal since the last decades [1]. They have individual physical attributes and mechanical characteristics, suchlike high specific stiffness and strength, perfect plastic energy absorption at a low weight, and superior corrosion resistance together with high damping [2]. Fabrications based on these lightweight materials are almost new and unknown; though in the past few years, these metallic foams provide notable potential applications in various industries.
