Convergence of a\(L_2\) displacement error in \(\vec {v}_0(\vec {X})\), \(t = 1\), b\(L_2\) micromorphic error in \(v_1(\vec {X})\), \(t = 1\), and c error in energy evolutions \({\mathcal {E}}(t)\), \(t \in [0,1]\). d Reaction bending moment M(t) for Q4G1 and various element sizes h in comparison with the reference solution. Data points for T6G6, \(h=1\ell \), are missing, because this solution is considered as the reference solution and the corresponding error thus vanishes
