Geometric frustration offers a pathway to soft matter self-assembly with controllable finite sizes. While the understanding of in assembly derives almost exclusively from continuum elastic descriptions, current challenge is understand connection between microscopic physical properties misfitting "building blocks" and emergent behavior at mesoscale. We present analyze particle-based description what arguably best studied example for frustrated assembly, negative-curvature ribbon observed both assemblies chiral surfactants shape-frustrated nanoparticles. Based on our particle model, known as saddle wedge monomers, we numerically test shape interactions subunits supra-particle scale, specifically focussing propagation relaxation inter-particle strains, role extrinsic ribbons equilibrium regime width selection. Beyond intuitive misfit, show that self-limitation critically dependent range cohesive interactions, larger size requiring increasing short-range interparticle forces. Additionally, demonstrate non-linearities arising discrete alter self-limiting due strain-softening shape-flattened partial yielding highly strained bonds, which turn may give rise states hierarchical, multidomain assembly. Tracing regimes frustration-limited specific features shapes provides necessary guidance translating theory size-programmable into design intentionally-frustrated colloidal particles.
