An in situ quantitative tensile testing platform is developed to enable the uniform in-plane loading of a freestanding membrane of 2D materials inside a scanning electron microscope. The in situ tensile testing reveals the brittle fracture of large-area MoSe2 crystals and measures their fracture strength for the first time.

در این پروژه نمونه های مختلفی از نانوکامپوزیت های پلی ایمید تقویت شده با درصدهای مختلف نانو ذرات اصلاح شده اکسید آهن از یک تا پنج درصد وزنی به روش درجا به طور موفقیت آمیزی تهیه شدند. ماتریس پلی ایمیدی به کار رفته در تهیه نانوکامپوزیت ها از طریق واکنش تراکمی بین بنزوفنون 3،′3،4،′4-تتراکربوکسیلیک دی¬انیدرید و 3،′3 دی آمینو دی فنیل سولفون در حلال دی متیل استامید تهیه شد. بهینه سازی کامل هندسی پلی ...
Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is ...

Rapid heat cycle molding (RHCM) is a special molding process capable of producing molded plastic parts with high surface quality and improved weldline strength and appearance. This study investigated the influence of the weldline on the tensile strength of RHCM and conventional injection molded (CIM) components. The test specimens with and without a weldline were cut from RHCM and CIM parts for...
The mechanical properties of wrought iron from multiple elements of six late 19th-century truss bridges is evaluated by a program of destructive and nondestructive testing, including hardness testing and tension tests to evaluate the yield stress (Fy), tensile strength (Fu), and ductility of the material. The yield stress and tensile strengths are found to be in accordance with those published ...
Myocardial infarction was experimentally induced in rat hearts and harvested immediately, 7, 14 and 28 days after the infarction induction. Anterior wall infarct samples underwent biaxial tensile and uniaxial compressive testing. Orientation of collagen fibres was analysed following mechanical testing. In this paper, we present the tensile and compressive stress-strain raw data, the calculated ...
in this research, the effect of 2.3 wt.% aluminum addition on the microstructure and tensile properties of high manganese austenitic steel fe-18mn-0.6c was studied. for this purpose, the samples were investment cast, homogenized and hot rolled. tensile testing was carried out at ambient temperature. microstructural investigations and fractography on the steel samples were carried out using an o...
