Helpful Hints and Tips: Converting from Shear to Normal Stress-Strain Diagram
Abstract: The study of stress and failure of adhesive-bonded composite and metal joints usually involves the computation of a material nonlinear problem. Typically, experimental data on adhesive material properties are given in the form of shear stress-strain curves. The relationships in this resource allow the user to convert the material properties fitted in the shear stress-strain condition to their equivalent for a uniaxial stress-strain condition and vice versa.

“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck®. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”
