We propose an extension of the uniform approximation approach towards the simultaneous truncation of the associated dual energy. In the talk, we derive a hierarchy of approximating theories and corresponding a‐priori error estimates for their solutions, for the special case of an isotropic, linear elastic, one‐dimensional structural member with rectangular cross‐section.
