The use of nonlinear projection matrix in co-rotational (CR) analysis was pioneered by Rankin and Nour-Omid 1990s (Computers & Structures, 30 (1988) 257-267; Comput. Methods Appl. Mech. Engrg., 93 (1991) 353-384), has almost became a standard manner for CR formulations deduction over the past thirty years.

Knowledge sharing and transfer are essential for learning in groups, especially when group members have different disciplinary expertise and collaborate online. ComputerSupported Collaborative Learning (CSCL) environments have been designed to facilitate transactive knowledge sharing and transfer in collaborative problem-solving settings. This study investigates how knowledge sharing and transf...
