The Figure below depicts two instance of a pull test. In (a) a stiffer material (steel rod) is pulled out of a softer one (concrete block); in this case the load transfer diagram shows a rapid variation near the inner end of the rod. In (b) a softer material (plastic rod) is pulled out of a stiffer one (concrete block), and the load transfer diagram is reversed. If the test is to be simulated by a finite element model, indicate for (a) and (b) where a finer mesh would be desirable. Explain.
