Interface component analysis is a unique feature that helps to speed design variation studies for non-structural components using a model fragment of the full system model. It works by first storing the displacement time history of user-defined nodes to a disk on a file system. The stored file is a binary file and its name…
A powerful feature of LS-DYNA v970 and beyond that has yet to gain widespread popularity is the *CASE keyword. Here are two examples to highlight the use of *CASE. Sequential and Independent Simulations Ex: Head Impact (FMVSS 201) *keyword $ $ Impact 1 $ *case_begin_1 *title position 1 impact *include vehicle_model.i *include head_position_1.i *case_end_1 $…
Honeycomb cell structures are popular among weight conscious designers due to their high strength to weight ratio. In the automotive space, aluminum based honeycomb structures are widely used to represent barriers to simulate a controlled energy absorption. Honeycomb structures are highly anisotropic and requires adequate testing to characterize them. This post focusses on the characterization…
