Molecular Dynamics, finite element methods, and Monte Carlo ensemble simulations (GROMAC)

...molecular dynamic simulations help with microscale, while programs such as LS-Dyna could be used for macroscale simulations...

COMSOL Multiphysics for its comprehensive multiphysics simulation capabilities but for more structural and thermal focused modeling, ABAQUS and ANSYS serve as robust platforms for finite element analysis and simulation

I am slightly confused by the relation of dislocation density and yield strength of a metallic alloy. Sources tell me that one of the principles to harden a metal is to make dislocations more dense, to increase the stress field. For example by cold working. Now, another source tells me that a microstructure with large grains is weaker, because dislocations cannot pass the grain boundaries and generate a severe stress field, which decreases the yield strength/ hardening. Isn’t that stating the opposite? Which one is true? Thank you in advance.

Although I will be sending an e-mail directly to both McLaren applied and McLaren F1 teams directly; I am not particularly hopeful they will respond.

Where else could I find information about mallite? Which was a material they used in the 1960's made of balsa wood and Duralumin (aluminum alloy). Even the wikipedia article is sparse in citations and primary sources. I will also post this in r/McLarenFormula1

Thanks for any help. Even if it just reading.
