Summary on Grant Application Form
Loss of SI in pultruded profiles has been observed in tests on beamg/columns to be a consequence of the growth of buckling deformations, leading to catastrophic failure, eg.tearing at web-flange junctions. The extent to which deformations and strains develop prior to damage initiation and during damage progression to eventual failure, are neither understood, nor can they be predicted by analysis, nor do rules and guidance exist for use in design. The proposed research aims to address all of the foregoing aspects of buckling-triggered failure in GRP and HF profiles (first and second generation profiles respectively) via an integrated programme of research. A database of bucklihg-triggered failure initiation and damage progression will be obtained from tests on beams and columns. Conventional and novel local and whole-field techniques will be used to capture critical quantities (strains etc) during damage intiation and progression in both GRP and HF puftruded beams/columns. Simple local-postbuckled plate analysis and nonlinear FE analysis will form the bases on which modelling capabilities will be developed for predicting the SI characteristics observed in the tests. Successful calibration of the analysis tools with the test database will allow them to be used to conduct parameter studies to define the limits, expressed in terms of geometric and material characteristics, of particular buckling-triggered failure modes and also to distil from them rules and design guiidance for the prediction of the budding-triggered failure resistance of GRP and HF profiles.
