The tensile properties of the colon have been examined using methods which gave repeatable results. They showed little change after storage in salt for up to five weeks. The burst strength remained unchanged along the length of the colon. The tensile strength fell distally, as the thickness of the colonic wall increased. The width at burst decreased distally as did the internal diameter. The vi...

نانو لوله های کربنی (nnt)به دلیل دارا بودن خواص فوق العاده مکانیکی، حرارتی و الکتریکی شان بسیار مورد توجه قرار گرفته اند. با جاسازی، همراستاکردن و توزیع یکسان نانو لوله ها در نانو الیاف الکتروریسی شده می توان این خواص را به ساختارهای با نظم بالاتر انتقال داد. در این تحقیق لایه نانو الیاف پلی اکریلونیتریل (pan) حاوی نانو لوله های کربنی تک جداره (swnt) با موفقیت الکتروریسی شد. ابتدا با استفاده از...

As emerging advanced construction materials, strain hardening cementitious composites (SHCCs) have seen increasing field applications recently to take advantage of its unique tensile strain hardening behavior, yet existing uniaxial tensile tests are relatively complicated and sometime difficult to implement, particularly for quality control purpose in field applications. This paper presents a n...

in this paper, we use molecular dynamics and finite element simulations to determine the mechanical properties of single-crystal metal of silver (ag) with nano-holes. the lattice transition method from 3-dimensions into 2-dimentions in molecular dynamics simulation as well as plane stress model in finite element method, is used to lessen the simulation time consuming. elasticity module reductio...

Al-0.9Si-0.6Mg (wt%) alloy conductive wires were designed and produced by continuous rheo-extrusion process. The effects of different heat treatment on microstructure, mechanical and conductive properties of the wires were studied. Results show that, after T6 heat treatment, conductive property of the alloy increased while elongation decreased with the higher aging temperature and longer aging ...

This paper attempts to investigate the influence of the microstructure and mechanical property changes on sand casting and permanent die casting alloys by grain refinement, modification combined action of both (Al– 3Ti–1B + Al–10Sr) and without grain refinement and modification effect. The microstructures of the castings are studied by optical microscopes. The microstructure and mechanical prop...
