Composites in structures - Use of special strength theories based on the form of anisotropy

Almost all materials currently used in construczion industry belong to the group of composite materials. These materials may be traditional ones, usually made of wood, stone, concrete or brick or modern ones, which are increasingly represented by polymer composites. When studying resistance os such materials to mechanical load, it is important to define the form of naisotropy, and an acceptable strength theory - based on analytical and experimental method - that will assist use in the analysis of the limit state of materials whwn subjected to compex mechanical load. The limit state analysis for an ortotropic fibre- based composite was conducted by experiment, and the results obtained were numerically verified based on the second order strength theory. The validity of the selected strength theory was confirmed by complex experimental study, involving multi-axial loading of appropriate material components.
