Simulation of Aluminium Foam Compressive Properties

Abstract:

In this paper, the simulation of the commpress properties of Al foam was investigated by finite element methods. The simulation results show that the compressive yield strength of Al foam is consistent with the theoretical model of Gibson and Ashby. The yield strength of Al foam decrease with the increase of porosity, and the yield strength decreases significantly with the increase of porosity. The density of Al foam is proportional to the compressive strength. At a certain porosity, the ratio of sample size and the aperture have an extremely important effects on compressive behavior of aluminum foam. When 4 ≤ D / d <8, with the increase of the ratio of D / d, the plastic deformation plateau and the compressive strength of metal foam is increasing ; on the contrary ,when the ratio> 8, with the increase of the ratio, the plastic deformation plateau is decreasing, the compressive strength keeps constant.

Analysis of Failure Mode of Masonry Wall under Vertical Compressive Stress

Authors: Hui Hui Zhao, Wen Fang Zhang

Abstract: The application of ABAQUS finite element software non-linear finite element analysis of brick masonry walls with structural column. Build three brick masonry wall models, and analysis of the damage form of the wall under different vertical compressive stress and horizontal force. Thus the analysis result compared with the calculation result of the relevant specification formula, in order to get validate compression influence of masonry aseismic walls. It turned out that different vertical compressive stress effect the shear capacity, and failure mode of brick masonry wall structure with a structural column.

Review the Research Trends and Application in Car Body of Aluminum Foam

Authors: Cong Cheng Ma, Feng Chong Lan

Abstract: Aluminum foam has been widely used in aviation and spaceflight, ships, cars, transportation, construction, petrochemicals, telecommunications, etc. For decades, scholars have done a lot of research work. Mature and stable production preparation process of aluminum foams has been possessed. At present, the practical application design and production has becomes a hot issue. Based on analysis a flood of literature, aluminum foams owned mechanical properties and application, property evolution after filling thin wall tube; all were inductive research and reviewed in the paper. Moreover, material structure design factor, experimental comparisons, application in the automobile industry, development situation, as well forecasted its market prospect, all this were summarized. Suggestions on aluminum foam applications in the automotive industry had been proposed. Consequently, promote the process of the research efforts on the application of aluminum foam in the car, provide to designer and research worker with reference.

Design of Functionally Graded Beam of Aluminium Foam for Civil Structural Application

Authors: Gianpaolo Perrella, Diana Faiella, Giuseppe Brandonisio, Massimiliano Fraldi, Elena Mele

Abstract: Sandwich foam beams, made of solid skins and aluminium foam core, are usually applied in high-tech engineering field while they are not yet adopted in civil structures. An initial, explorative study on the structural application of metal foam is presented in this paper. The potentials of sandwich foam beams are studied through analytical models and parametric analyses; the sensitivity of the flexural response of the media to the total amount of pores and their spatial distribution are investigated. An analytical tool able to design functionally graded beams of metallic foam is presented and applied with reference some commercial aluminium foams. An experimental campaign is being planned to validate the presented results.
