Causal Boxes and Hierar hi al Time Boxes

مطالعه تطبیقی تزیینات و فنون اجرایی در صندوق چوبی قبر شیخ صفی‌الدین اردبیلی و شاه اسماعیل اول صفوی

Sheikh Safi al-Din Ardabili and Shah Isma’il I Safavid grave boxes are from the wooden works of Timurid and Safavid eras respectively. Their current location is the tomb of Sheikh Safi al-Din Ardabili, located in Ardabil. These two grave boxes provide a context to implement various decorations of geometric, herbaceous, petroglyphs, and wood-related techniques, that their identifying and analyzi...

The Effect of Fe Additive on Plastic Deformation for Crush-Boxes with Closed-Cell Metal Foams, Part II: Al-Composite Foam-Filled brass tubes Compression Response

The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...

Effect of Fe additive on plastic deformation for crush-boxes with closed-cell metal foams, Part I: Al-composite foam compression response

AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...
