This work aims to be useful for future experiments providing hydrodynamic and stopping power calculations to warm dense matter (WDM) analysis. For this purpose, the hydrodynamic simulations have been carried out using MULTI-fs code. Key plasma parameters - e.g., electron temperature, mass density, ionization, etc- have been studied at different expansion times to show the WDM behavior. Thanks to these data from the hydrodynamic simulations, precise stopping power calculations can be performed. A comparison is made between our present stopping power model with other models in the literature at the Bragg peak. Specifically, proton energy loss is estimated in carbon at a WDM state described by the hydrodynamic simulations. As the Bragg peak is the energy range where most differences arise between theoretical stopping power models, an experiment of the characteristics here described could be useful to differentiate between these models and to test their validity in the WDM regime.
