Unexpected zigzag plot on cantilever beam, expected a smooth sin curve

I am fairly new to COMSOL and I am in need of the communities help.
I am running Solid Mechanics Physics, with a 'Linear isotropic hardening' plasticity model.
I am running the 'Time Dependent' study in the range(0,0.01,1)
The cantilever beam is fixed in one end and subjected to a harmonic load on the other end [see attached Figure 'beam.png']. In this Figure, the 'Point of interest' is where the strain in the x-direction is plottede.
I am trying to plot the strain development in this point on a cantilever beam, using a Time-dependent study. The resulting plot of the strain is zigzag instead of a smooth sin curve.
I have tried running the time-dependent study with more steps, but this does not help [see attached Figure 'strain_displacement.png'].
Thanks
