Evolution of the stress σx in time at point A (a1) and the vertical displacement at point B (a2) for different values of the kon, koff parameters of the material (a1). Stress field σx (in Pa) at t = 5s for the case kon = 0.2, koff = 0.2 (b), kon = 0.2, koff = 0.4 (c) and kon = 0.2, koff = 0.8 (d); stress patterns along the clamped cross-section of the beam at t = 2s(e) and t = 5s(f).
