Chareyre proposed the following answer:
Of course, stiffness is a physical parameter and changing it may affect
(or not...) the results. Ultimately the number of particle is the only
parameter you can play with.

However, if wangxiaoliang is targeting a final strain of 0.3, he is probably not focusing on the elastic regime. 
If the confining pressure is small compared to the stiffness of silicates (10e11), stiffness can most likely be decreased by a few orders of magnitude without any change in peak strength, residual strength, dilatancy, etc. It's all a matter of modelling methodology and wise compromize. The best model is useless if it can't be computed...
