Original abstract
Collective stress generation in cellular monolayers is a key phenomenological process governing coordinated migration and emergent multicellular dynamics. We employ a generic active nematics model to investigate stress generation and its associated properties. By analyzing the maximal principal stress and its correlation with the nematic director across different activity strengths, we find that the principal stress aligns perpendicular (parallel) to the nematic director for extensile (contractile) activity. In the turbulent regime, we identify a distinct isoline derived from anisotropic stress components along which all $\pm 1/2$ defects (both nematic and stress) are localized. This feature is robust and remains unchanged with variations in both the magnitude and nature (extensile or contractile) of activity. Our findings provide a new route to probe the mechanical and rheological properties of confluent cell layers, where stress measurements are more accessible than detailed cell shape or size characterization.
