| 摘要： | This report documents the evaluation of a new soil material model intended for roadside safety simulation applications using the nonlinear finite element code LS-DYNA. This report concentrates on the 18 parameters required for the soil material. The focus is on obtaining the appropriate parameter values (through testing or by analytical means), providing an engineering understanding of the parameters, and providing bounds for the effects of varying the parameters. Although extensive progress has been made on the soil material model, there is considerably more to be accomplished before the model would be effective in most roadside safety applications. The companion manual to this report is: Manual for LS-DYNA Soil Material Model 147 (FHWA-HRT-04-095). |
