Summary on Grant Application Form |

The primary area of research that this proposal covers is the failure of adhesively bonded joints under service loading conditions; specifically the separate cases of low frequency fatigue and environmental degradation. The equipment requested will be used to generate a) high quality material data for input to subsequent numerical analysesb) the response characteristics of bonded structures to service loads used to validate the results of the numerical analyses, andc) failure parameters that can be incorporated with the numerical analyses to predict the strength of the structures. The material data discussed in a) will include repeated load-dwell recovery-dwell tests which will be used to generate parameters for a visco-plastic material model used in the analysis of bonded structures subjected to low frequency fatigue. Also constitutive data for adhesives at varying levels of moisture saturation will b measured and used to define the material response in the coupled mechanical-diffusion analyses that investigate the environmental degradation of structures. The testing referred to in b) above will be undertaken on a range of joints representative of bonded structures found in the aerospace, automotive and structural sectors. These will be subjected to low frequency cyclic loading or tested to failure after exposure to various environmental conditions. In both cases the response will be characterised by local and global compliance measurements and video microscopy techniques. The failure parameters mentioned in c) above include creep rupture strains and fracture tests to provide data on the degradation that occurs at the adhesive interface. These then will respectively be used to predict the failure of structures under low frequency fatigue and the residual strength following environmental degradation.
