2. Benchmark solution

2.1. Calculation method used for the reference solution

Since the loading history is very simple, the reference results can be obtained manually by applying the algorithms presented in the reference document [R7.04.01].

2.2. Benchmark results

The counting of the elementary cycles by the RCCM method leads to:

Nb_Cycl = 2	Cycle 1	Vale_Min:	-500.	Vale_Max:
	Cycle 2	Vale_Min:		Vale_Max:
