EN

A methodology for the assessment of periodic composites under variable repeat loads by means of the shakedown theory is presented and applied to metal-matrix-composites. The approach is based on the local shakedown analysis in a representative volume element of the composite and the use of averaging techniques to determine the domains of admissible stresses on the macro-level.

W pracy zaprezentowano metodologię oceny kompozytów o strukturze periodycznej przenoszących zmienne, powtarzalne obciążenia na podstawie teorii przystosowania w zastosowaniach do kompozytów z metalową osnową. Metodologię oparto na lokalnej analizie przystosowania dla reprezentatywnego elementu kompozytu i zastosowaniu technik uśredniających w celu określenia dopuszczalnych naprężeń na poziomie makroskali.
