Abstract: According to the new engineering concept, the personnel training takes a combined learning mode, as an important trend of teaching reform in universities. The cloud teaching materials are the teaching resource, consisting with the combined learning mode. The preparation of cloud teaching materials of engineering mechanics is based on the OBE education concept, with the learning objectives, and integrating rich media digital publications, the cloud service and the mobile learning, to provide appropriate teaching resources for hybrid teaching of engineering mechanics. The practical application shows that the cloud teaching materials of engineering mechanics can arouse the students' interest in learning and enhance their autonomous learning.
