For civil engineering postgraduate entrance examination, such as structural engineering: what is the difference between structure and material strength? Will that high cost performance affect the future research direction? - After that, structural mechanics mainly studies the structure and stress of houses, which is especially important for steel structures and is also a very popular specialty. Material mechanics mainly studies building materials, which has great potential, but it is difficult to develop. Generally speaking, the study structure is good and the starting point is high, so it is easier to transfer to other majors in the future.
