A new cohesive element formulation is proposed for modeling the initial elastic response, softening, and failure of finite-thickness adhesives. By decoupling the penalty stiffness of the cohesive zone model formulation and the physical adhesive modulus, the new formulation ensures proper dissipation of fracture energy for opening and shear loading modes and mixed-mode loading conditions with any combination of elastic and fracture material properties. Predictions are made using the new element formulation for double cantilever beam, end-notched flexure, mixed-mode bending and single lap joint specimens with varying adhesive thicknesses. Good correlation between all predictions and experimental results was observedThe first author would like to acknowledge the FPU program grant AP2010-0977 from the Spanish Ministerio de Educación,
