| Abstract: | In this paper, the stress and strain fields of adhesive bonded structures are investigated by finite element method for simulating the vein of straligraphic rock layers. The creep behaviour of adhesive is also considered in the analysis. Numerical results are presented for typical adhesive bonded joints with different adhesive lengthes. The results show that the creep behaviour of adhesive affects the stresses and displacements in the adhesive bonded stractures considerably. |
