Ar+Ni and Ni+Ni collisions are investigated between 32 and around 100A MeV incident energy 
with the 4pi multidetector INDRA. Fusion cross sections are found to decrease from ~ 180 mb 
at 32A MeV to zero above 50A MeV. Other experimental results, for light systems, are compared. 
Moreover, theoretical works are discussed and fusion cross sections, calculated from two 
dynamical simulations based on nuclear Boltzmann equation (Boltzmann-Nordheim-Vlasov and 
Landau-Vlasov models), are also compared to experimental results
