This paper is concerned with monotonic and load reversal deformation of four dual-phase (DP) 590, 780, 980, 1180 one martensitic (MS) 1700 steel sheets. While the data are presented for all steels, provided DP 1180. Particularities pertaining to including decreasing hardening rate during forward tension, a linear then non-linear unloading, followed by Bauschinger effect, shift in continuous str...
the global environmental concerns have put the light weighting of structures on the fore front of the research in transportation industry. among other light weight alloys, the transportation industry is considering magnesium intensive light body-in-white structure in automotive applications. although the research in modeling technique areas is very active, a suitable practical model mimicking t...
Abstract The influence of pre-strain on the very-low-cycle loading behavior as occurring, for example during roller leveling sheet metals, is not yet fully understood. A key factor in this context stiffness material and its changes upon processing. To study general mechanical property low-cycle with small amplitudes a wide variety samples mild steel DC01, pure copper CU-DHP α -titanium are subj...
The detailed contribution of microstructural-level phenomena, such as dislocation structure development and annihilation, well inter-granular intra-granular backstress fields, to reverse loading behavior in metal alloys remains an area active research debate. ability predict unloading nonlinearities, the Bauschinger effect (BE), changes hardening rates during is necessary for accurate modeling ...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
هدف این مطالعه تعیین کردن این مساله است که آیا فراگیران فارسی زبان قادر به تطبیق پارامتری ضمیر موصولی that در جملات ساده و پیچیده ی انگلیسی در سایه اصل دستور جهانی هستند یا خیر. به علاوه نقش جنسیت در رابطه با آزمون تشخیص درستی یا نادرستی جملات دستوری مورد بررسی قرار گرفت. داده ها از 54 دانشجوی فراگیر زبان انگلیسی در دانشگاه فردوسی مشهد گردآوری شد. شرکت کنندگان در آزمون شامل 28 زن (51.85 درصد)و ...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
