Abstract - A unit cell based numerical approach is used for investigating fiber arrangement effects on the microscale stress and strain fields and on the overall thermomechanical response of a continuously reinforced unidirectional B/Al MMC. Simple periodic fiber arrays, clustered hexagonal configurations as well as modified and clustered square geometries are considered. The mean values and standard deviations of microstress and microstrain parameters in the matrix are computed and discussed for axial and transverse mechanical loading as well as for thermal loading.
