Library of Advanced Materials for Engineering (LAME) 4.54

Lester, Brian T.; Scherzinger, William M.

Accurate and e ffi cient constitutive modeling remains a cornerstone issue fo r solid mechanics analysis. Over the years, the LAME advanced material model l ibrary has grown to address this challenge by implementing models capable of describing mat erial systems spanning soft polymers to sti ff ceramics including both isotropic and anisotropic respons es. Inelastic behaviors including (visco)plasticity, damage, and fracture have al l incorporated for use in various analyses. This multitude of options and flexibility, however, comes at the cost of many capabilities, features, and responses and the ensuing complexity in the re sulting implementation. Therefore, to enhance confidence and enable the utilization of the LAME lib rary in application, this e ff ort seeks to document and verify the various models in the LAME library . Specifically, the broader strategy, organization, and interface of the library itsel f is first presented. The physical theory, numerical implementation, and user guide for a large set of m odels is then discussed. Importantly, a number of verification tests are performed with each model t o not only have confidence in the model itself but also highlight some important response cha racteristics and features that may be of interest to end-users. Finally, in looking ahead to the fu ture, approaches to add material models to this library and further expand the capabilities are pres ented.
