Summary on Grant Application Form |
|
Collaboration with Dalian University (DUT) is a major force multiplier with them providing half of the innovation and most of the manpower under Chinese, Royal Society, British Council and UWCC funding. Ten 1990-93 DUT visitors to Cardiff producing 26 technical papers, plus a new three year agreement covering this application's programme, underpin the collaboration. Every one of the following nine programme stages involves innovative theory based on recent previous innovation at Cardiff and/or DUT by: (1) Extending the Williams-Wittrick algorithm to eigenproblems of wave propagation along prismatic structures involving; (2) developing exact wave propagation strip elements for plan stress/strain, bending and Reissner-Mindlin theory; (3) developing approximate (FEM) elements to complement these including triangular and quadrilateral prisms; (4) using the applicant's existing software and/or skills to develop a test bed computer program for prismatic thin-walled structures to test all aspects of this application; (5) hence solving power flow problems; (6) wave scattering problems; (7) localised vibration problems; (8) forced vibration problems and; (9) with a major emphasis on solving random wave propagation problems. The test bed software results should benefit aerospace designers of stiffened panels in jet exhaust regions.
