As an adverse effect, vascular channels cause a disturbance in the fibers around the channel region. In this study, first, the fiber orientation around the channel is evaluated using micro-CT images analyzed with VoxTex software. Variation in the stiffness around the channels is determined using micro-homogenization. The results revealed orientation disturbance in the out-of-plane direction with a maximum of about 6 degrees. The micro-channel affected the nearby local stiffness as well, reducing it by up to 19%.EnglishMicro-CT analysis; Fiber orientation; Microvascular channels; MicrostructureINTERNAL STRUCTURE; VOXEL MODELS; POLYMER; BEHAVIOR; TENSILE; DAMAGEArticle
