In Chapter 3 we have seen that the mathematical modelling of a continuously supported plate subjected to a moving load (Figure 4.1) involves coupled equations for the plate and for the supporting fluid base. The moving load is included by considering its weight and possibly its inertial effects. The purpose of this chapter is to introduce the reader to the subject area of moving loads over floating ice covers, by first discussing some relatively simple historical examples to illustrate certain mechanical and mathematical features of problems of this type. This discussion therefore anticipates some aspects of the more complete theory that we approach towards the end of this chapter, and then develop systematically in Chapter 5.
