بررسی تجربی و عددی توانایی ماده ی جدید از آلومینیوم ریختگری و ذرات پوکه معدنی در کاهش موج شوک
Abstract - Some materials, due to their inherent properties, can be used as shock and wave absorbers. These materials include foam and porous materials, in this study, specimens were made by casting aluminum on porous mineral pumice Which can replace aluminum foam in some applications with lesser cost, at first, the material is compared with aluminum foam using compression test and quasi-static loading diagram Which compares the diagrams of these two materials showing the similarity of their behavior in quasi-static loading. Initially, the elastic bending of the walls causes an elastic region in the stress-strain curve of the material Then, the plastic collapsing of the cells forms a large and relatively smooth region along the elastic and after the plastic collapse of the cells, the area known as foam densification begins where the density of the foam (ρ0) closer to the density of its constituent material (ρa) causes a sudden increase in the stress level in the specimen. thes ...محصولات مرتبط در دستهبندی "فنی و مهندسی"
