Wikiversity:Guided tour/Main Page

Wikiversity is a Wikimedia Foundation project devoted to learning resources, learning projects, and research for use in all levels, types, and styles of education from pre-school to university, including professional training and informal learning. We invite teachers, students, and researchers to join us in creating open educational resources and collaborative learning communities. To learn more, try a guided tour or start editing now.

Today's Featured Project

Nonlinear finite elements is a course of about 150 to 200 pages designed by mechanical engineering researcher User:Banerjee. It is the best developed of a number of related mechanical engineering projects created by the same user - other projects include Introduction to Elasticity (about 100 pages) and Waves in composites and metamaterials (a 25-page lecture series). Nonlinear finite elements contains a lecture series, homework assignments and solutions. Course description: "an introductory course on nonlinear finite element analysis of solid mechanics and heat transfer problems. Nonlinearities can be caused by changes in geometry or be due to nonlinear material behavior. Both types of nonlinearities are covered in this course. The course aims to (1) provide the mathematical foundations of the finite element formulation for engineering applications (solids, heat, fluids) and (2) expose students to some of the recent trends and research areas in finite elements." For related materials, see also continuum mechanic, finite element analysis and nonlinear finite elements (category).

Development

At Wikiversity we are committed both to conventional learning patterns and resources, and to innovation and experimentation. Wikiversity is open to reconceptualising how web education can occur and how open educational resources can be made, and we are open to new ideas about the use of the Mediawiki environment for learning and research. Check out and help develop our learning projects and how learning works on Wikiversity, see how Wikiversity can help you, and explore how to get involved and start adding content. The sandbox server project is also a centre of learning experimentation.
