Bio-corner: Bio and Thin-walled Structures Thin-walled structures often occur in biological applications, from the meso-scale of bone structure down to the nano-scale of cell cytoskeleton networks. The large range of active research at Johns Hokpins in "nano" and particularly "bio" applications affords a variety of interesting collaborations. See Professor Schafer's vitae for research on the stability of bones and cytoskeleton networks. Learn more about bio related institutes that Professor Schafer is affiliated: INBT: Institute for Nano Bio Technology IMMBI: Inst. for Multiscale Modeling in Biological Interactions For students interested in working in these cross-disciplinary areas Professor Schafer is affiliated with NBMed, the Howard Hughes Medical Institute Graduate Training Program at Hopkins. Current Hopkins students as well as prospective students may apply. Students should have significant strength and interest in computational modeling. |
What are Thin-Walled Structures? Scopus RSS Feed of Recent Papers News from the Group Sheathing Braced Wall Design Report (February 2013) Our extensive research on sheathing-braced cold-formed steel walls has recenrly wrapped up. All of the project information is available here, or jump directly to the final report. Complete design examples are provided for the design of CFS walls that employ sheathing to successfully brace the studs. CFS-NEES Reports Posted (January 2013) Our cold-formed steel earthquake engineering research project has been busy. New research reports detailing the CFS-NEES archetype building, shear wall testing, moment-rotation behvaior of beams, and fastener-sheathing testing as well as other recent research progress are all available. Go here to learn more about the project and here to jump directly to all the great publications. US-Egypt CFS Workshop Success (December 2012) Egypt is in political turmoil. Making a difference in these times is probably asking too much from a small joint USAID/NSF research project, but for two days (9-10 December) approximately 200 Egyptian engineers, architects, builders, and manufacturers and even a few ministers from the Egyptian government met at the University of Cairo to imagine a future for Egypt that takes advantage of the latest technology: light (cold-formed) steel framing. The workshop was led by the United States and Egyptian project teams and included key participation from the United States Industrial Advisory Board. Four members of that board: George Richards (BORM), Don Allen (DSi), Nader ElHajj (Framecad), and Nabil Rahman (TSN), came to Cairo to share their experiences. Learn more.
Coupled Instabilities 2016 (December 2013) The Thin-walled Structures Group has agreed to host the Coupled Instabilities in Metal Structures conference series in 2016. More details forthcoming. CUFSM 4.05 Updated (Summer 2012) We have updated the new standalone version of CUFSM (version 4.05) now available online for free download. CUFSM 4.05 provides a sweeping expansion to the capabilities of our popular finite strip program - now the local, distortional, and global buckling loads of thin-walled members can be explored for general end boundary conditions. This expansion allows for much more difficult problems to be explored providing new insights for researchers and engineers. For more on CUFSM 4 go here, for more on FSM research go here.

CUFSM 4 Standalone Released (October 2011) We have released the new standalone version of CUFSM (version 4.04) now available online for free download. CUFSM 4.04 provides a sweeping expansion to the capabilities of our popular finite strip program - now the local, distortional, and global buckling loads of thin-walled members can be explored for general end boundary conditions. This expansion allows for much more difficult problems to be explored providing new insights for researchers and engineers. For more on CUFSM 4 go here, for more on FSM research go here.
