The 2D weave structure is simplified as a crossply structure and a fiber bundle undulation structure. Based on the matrix strength stochastic distribution theory and the fiber failure stochastic distribution theory, the stress-strain behavior and the tangent tensile modulus are obtained for unidirectional composite (0$^\circ$ ply). With the relationship between crossply and unidirectional ceramic matrix composite with the same material, the stress-strain behavior of crossply ceramic matrix composite can be obtained. A two-dimensional analytical method is proposed for fiber bundle undulation structure. With the composite strength model, the undulation structure is divided into sub-elements. The failure analysis is carried out considering the failure of different sub-elements in the fiber bundle undulation structure. Moreover, the stress-strain behavior of the undulation structure is obtained. Combining the crossply and the undulation structure's stress-strain behavior, the stress-strain behavior of of the 2D weave ceramic matrix composite is obtained; and the result agrees well with the experimental result. %K ceramic matrix composite %K 2D %K fiber bundle undulation %K strength model
