Transformation Plasticity and Toughening
Analysis of the dynamic evolution of multilevel structure during martensitic transformations provides kinetics-based constitutive relations for transformation plasticity. Application in numerical modeling of ductile fracture by microvoid-softening-induced shear localization, in conjunction with metallographic study of crack-tip processes, identifies transformation toughening mechanisms operatin...
متن کاملModel of Transformation Toughening in Brittle Materials
Assuming that the energy dissipation decreases inversely with distance from the crack tip, the increase in steady-state toughness of a transformation-toughened ceramic is estimated to be AJ = (AJ,/w) In (1 + w), where (i) AJo denotes the toughness increment which would be expected for a given zone height h , assuming full transformation throughout the zone, and (ii) w is a nondimensional parame...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولFracture and toughening of soft elastic composite
Characterized by their low modulus and high stretchability, soft composites have recently attracted great interest from researchers in related areas. The main objective of the present study is on the fracture property and toughening mechanism of soft composites. Two types of soft composites will be studied: soft elastic foam and the double-network (DN) composite. A theoretical/numerical study i...
متن کاملToughening of thermoset polymers by rigid crystalline particles
The toughening of an aromatic amine-cured diglycidyl ether of bisphenoI-A epoxy with particles of crystalline polymers was studied. The crystalline polymers were poly(butylene terephthalate), nylon 6, and poly(vinylidene fluoride). Nylon 6 and poly(vinylidene fluoride) were found to toughen the epoxy about as well as did an equivalent amount of CTBN rubber. Poly(butylene terephthalate) was foun...
