- Аннотация: The method to develop failure modeling approach for laminated composite materials, based on degradation parameters is presented. All steps necessary to determine material damage characteristics and their influence on elastic properties of composites are described. An example of failure modelling approach utilizing only standard strength characteristics is demonstrated. It can be seen that proposed failure modelling approach based on formulated assumptions and utilizing only minimum experimental data gives a good correlation with the results of biaxial loading experiments. The approach has a block form and can be modified at all key steps such as elastic relations or first ply failure criterion. The calculations for examples with elastic and strength nonlinearity are also performed and a good correlation between theoretical and experimental dependencies are demonstrated. The approach permits to take into account different forms of physical nonlinearity, it has a block form and can be modified at all key steps to achieve required for practical purposes precision. https://www.scopus.com/inward/record.uri?eid=2-s2.0-85077603663&partnerID=40&md5=0483887adbbf8e36dd5d39a6ed79fa6f
