This paper describes the development and validation of a finite element model (FEM) of the SID-Ils (a small, second-generation side impact dummy) beta+- prototype dummy using a nonlinear explicit FE code. The geometry of the SID-Ils dummy is modeled with shell and solid elements from digital scans. The material properties are derived from dynamic tests, and the model validation is conducted on component, sub-assembly and full assembly levels. Component level validation of the head/neck, arm, ribs, and lumbar spine is presented. The model validation of the thorax and pelvis sub-assemblies as well as pendulum calibration tests (shoulder, thorax, abdomen, and pelvis) and rigid wall sled tests of the fully assembled dummy mode is also presented. The model response compares favourably with experimental data, and provides a reasonable level of confidence in the model biofidelity. (A)
