NUMERICAL EXPERIMENT ON SHEAR TESTING OF A CROSS-LAMINATED WOODEN ELEMENT

Abstract

A numerical experiment on shear tests of a model of a wooden CLT-panel revealed the possibility of visualizing the wave process of stress and strain propagation. Deformation as a process continuous in time is described discretely, in minimal time steps, with a visual display of a video sequence of positions in the space of the locus of tangent strain tensors. A qualitative and quantitative continuous wave pattern of stresses shows areas of the model volume where stress and strain waves arise and move. Stress isosurfaces are visualized. It is concluded that it is possible to divide the stress values expected in the numerical experiment into arbitrarily narrow intervals and separately monitor these processes in numerical models.
