  • we impose an embedding in \({A}_{1}\),

  • \({u}_{x}={D}_{0}\cdot y,{u}_{y}=0\) on edge \({A}_{1}-{A}_{3}\), \({u}_{x}=0\), \({u}_{y}={D}_{0}\cdot x\) and \(\mathrm{DRY}=0.0\) on edge \({A}_{1}-{A}_{2}\),

  • \({u}_{x}={D}_{0}\cdot y,{u}_{y}={D}_{0}\cdot L\) and on edge \({A}_{2}-{A}_{4}\), \({u}_{x}={D}_{0}\cdot L,{u}_{y}={D}_{0}\cdot x\) on edge \({A}_{3}-{A}_{4}\),

where \({D}_{0}=1.1{10}^{-4}\cdot f(t)\), and \(f(t)\) represent the amplitude of the cyclic loading as a function of the (pseudo-time) parameter \(t\), defined as (integration increment: \(5.0\times {10}^{-5}\)):
