| Abstract: | On the basis of stress-time curves from intens loadding experiment with light gas gun,some dynamic properties of cement stone are studied by improved Lagrangian analysis method(curved surface-fitting method),and many signifiiant conclusions,for examplle:stagnant-return phenomena of stress-strain curves,strain-rate effect and waveform dissipation are get. |
