Temperature and Geometry Dependence of Fracture Toughness in Euro Fracture Dataset
In this paper finite element simulations of fracture tests are carried out firstly to verify the experimental findings and secondly to examine and validate the proposed Global equations. This objective has been achieved ...
Measurement and Prediction of Residual Stress Generated by Local Compression
. In this paper local compression, or punching, is used to introduce a residual stress field into a cracked plate, and the resulting residual stress field determined using Finite Element Analysis (FEA). However, great care must be taken using this approach...
Dynamic Stability of Laminated Composite Plates with an External Smart Damper
The dynamic stability of a composite plate with external electrorheological (ER) damper
subjected to an axial periodic load is investigated. Electrorheological fluids are a class of
smart materials, which ...
Temperature and Geometry Dependence of Fracture Toughness in "Euro Fracture Dataset"
Reliable prediction of fracture conditions is a major concern in the integrity assessment
of structural components. This is specifically critical within the transition regime where there is a
significant ...
Evaluation of effective mechanical properties of nanocomposites reinforced with multiwalled carbon nanotube
An Investigation on Stiffness Analysis of a 3-PSP Spatial Parallel Mechanism with Flexible Moving Platform Using Invariant Form
In this paper, the stiffness of a 3-PSP spatial parallelmanipulator is investigated. Unlike traditional
stiffness analysis, themoving platformis assumed to be flexible. Two analytical methods are used
in ...
مقاومت الکتریکی و انرژی فعال سازی در ابررسانای PrO0.85FeAs
سازو کار میخکوبش شار ابررسانای PrO0.85FeAs ساخته شده تحت فشار بالا با دمای بحرانی Tc برابر با 38.4 کلوین در این مقاله بررسی می شود. وابستگی دمایی مغناطومقاومت در میدان های بالا تا 13 تسلا اندازه گیری گردید. پهن شدگی مقاومت الکتریکی در ناحیه گذار...
Position and stiffness analysis of a new asymmetric 2PRR–PPR parallel CNC machine
In this paper, structural stiffness analysis of a new 3-axis asymmetric planar parallel manipulator, a 2 P RR–P P R structural kinematic chain, is investigated. The manipulator is proposed as a tool holder for a 5-axis ...
اثر پارامغناطیس اسپین روی میدان بحرانی بالایی در ابررساناهای NdO0.82F0.18FeAs و PrO0.85FeAs
ترکیبات NdO0.82F0.18FeAsو PrO0.85FeAs به روش استاندارد حالت جامد تحت فشار بالا ساخته شدند. مقاومت نمونه ها در محدوده ی میدان های مغناطیسی صفر تا 13 تسلا اندازه گیری شد. میدان بحرانی بالایی و میدان برگشت ناپذیر را به ترتیب از روی معیار 90% و 10% افت...
