文摘

A novel homogenization procedure for thick shells is proposed Thick shell theory used in both micro and macro scales. Objectivity of structural softening response achieved with a 2-scale regularization. Out-of-plane loaded unreinforced masonry walls are analyzed with the proposed method. The homogenized response accurately represents out-of-plane failure of masonry.
