The survey described in the article revealed that HSE students establishing online communication with their peers from other countries often complain about sudden, unexpected communication breakdowns that they find difficult to explain and that are likely to occur due to the socio-cultural differences existing between communication partners in a multicultural learning community. Featuring different approaches to Massive Open Online Courses (MOOCs) among education policy makers, theorists and practitioners in the field and highlighting an increasing popularity of this educational phenomenon worldwide, the article provides a brief record of MOOCs’ success at Harvard University and the National Research University Higher School of Economics (HSE) making the authors move, This paper examines some of the particular challenges around licensing and intellectual property presented by the massive open online course (MOOC) movement. The MOOC focuses on the various types of metal forming operations.

INTRODUCTION TO SHEET METAL FORMING PROCESSES ... simulation Available on Udemy. If you are not familiar with the basics of the Friction Stir Welding process, you are requested to go through the previous two courses on the Friction Stir Welding process. Welcome to the course "Friction Stir Welding of Aerospace Alloys". 4. Metal forming processes Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. The main objective of this project is to model the single and double lap joints of FSWed Magnesium alloy similar joints and compare the thermal and stress distribution of both the joints. Plastic properties of metals are used during the process of metal forming. 3. That is the ability to change without damage the In. Observe mechanical, microstructural properties of similar and dissimilar metals. This presentation deals with the MOOC available on Udemy.

The tools used for such deformation are called die, punch etc. PDF | This presentation deals with the MOOC available on Udemy. cessing. Metal forming is the main method of making metal products and semi-finished products. 1. Basics of Friction Stir Welding process The MOOC focuses on the various types of metal forming operations. gradually towards the main focus of this paper – socio-cultural problems, that Russian students frequently face while taking a MOOC in English.

So they are advised to go through the lectures again before attempting them. The tools used for such deformation are called die, punch etc. In order to plastically deform a metal, a force must be applied that will exceed the yield strength of the material. The results of the survey presented in the article indicate that there is an urgent need to find effective ways to increase the students’ level of socio-cultural competence that would allow them to communicate successfully in a new virtual learning environment. Application of Friction Stir Welding process in aerospace industries. In this course you will learn about: Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. MOOC on Friction Stir Welding of aerospace alloys, Making a Creative Commons MOOC: Challenges and Opportunities.
