Fig. 9From: Numerical modelling of mechanical degradation of canvas paintings under desiccationVertical Displacement (U2) Plot: the maximum inward displacements are distributed around the middle of the longer stretchers (left) and the longer stretcher pulled inward eccentrically causing lateral torsional buckling, which is shown in the cross-section plot; the deformation is exaggerated by 5 times for the purpose of visualisation (right)Back to article page
