Claim 18:
19. The method of claim 1, wherein the finite element analysis model comprises an adjusted finite element analysis model and generation of the adjusted model comprises:
generating an initial finite element analysis model representing the honeycomb based crash barrier using an initial set of two-dimensional finite elements to represent the plurality of cells;
obtaining an initial numerical static strength using the initial finite element analysis model in a first static crash simulation;
determining the initial numerical static strength fails to satisfy a physical static crush strength included in the specification of the honeycomb based crash barrier;
adjusting, in response to the numerical static strength failing to satisfy the physical static crush strength, one or more properties of the initial set of two-dimensional finite elements to produce the adjusted model with an adjusted set of two-dimensional finite elements to represent the plurality of cells;
obtaining an adjusted numerical static strength using the adjusted finite element analysis model in a second static crash simulation; and
determining the adjusted numerical static strength satisfies the physical static crush strength included in the specification of the honeycomb based crash barrier.
