In this paper, we establish a multi-layer composite model to describe the biofilm mechanical inhomogeneity based on unified multiple-component cellular automaton (UMCCA) model. By using our model, we develop finite element simulation procedure for biofilm tension experiment. The failure limit and biofilm extension displacement obtained from our model agree well with experimental measurements. This method provides an alternative theory to study the mechanical inhomogeneity in biological materials. <\/jats:p>","DOI":"10.1142\/s0219720016500141","type":"journal-article","created":{"date-parts":[[2016,3,9]],"date-time":"2016-03-09T02:07:44Z","timestamp":1457489264000},"page":"1650014","source":"Crossref","is-referenced-by-count":4,"title":["Multi-layer composite mechanical modeling for the inhomogeneous biofilm mechanical behavior"],"prefix":"10.1142","volume":"14","author":[{"given":"Xiaoling","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, University of Science and Technology Beijing, Beijing 100083, P.
