Simulation for classical stiffened panel under pure shear load

Fixture design for classical stiffened panel under pure shear load was conducted. The panel assembled with fixtures under uniaxial tension was simulated by Abaqus software to achieve pure shear situation. Trying to improve computational efficiency, the FE (finite element)-model was analyzed comprehensively by 3D elements combined with 1D and 2D elements. The stress distribution of the whole model was analyzed by applying shear load in the plane of panel. The results showed that the distribution of the von Mises stress was centrosymmetrical in the whole model. Along the boundary line of stiffened rectangular panel core, the level of several kind of stresses little long away from the loading end was adjacent, respectively. The phenomenon was in accord with pure shear situation. The efficiency of load delivery from panel to reinforcing rib was achieved but low. The distribution of stress in region of loading bolts presented good symmetrical characteristic.
