Abstract:An elastoplastic damage model with rate effects was developed for wood and was implemented into LS-DYNA, a commercially available finite element code. This manual documents the theory of the wood material model, describes the LS-DYNA input and output formats, and provides example problems for use as a learning tool. Default material property input options are provided for southern yellow pine and Douglas fir. The model was developed for roadside safety applications, such as wood guardrail posts impacted by vehicles; however, it should be applicable to most dynamic applications.
