What is Jamming Transition in Soft Materials?

The jamming transition in soft materials is the critical phenomenon where disordered particle systems shift from a fluid-like to a rigid state at zero temperature and applied stress, marked by the onset of yield stress and scaling of viscosity and elasticity.

This transition occurs at random close packing density in colloidal and granular systems with finite-range repulsive potentials (O’Hern et al., 2003, 1563 citations). Researchers study shear jamming and rheological changes, as seen in shear thickening of suspensions (Wagner and Brady, 2009, 958 citations). Over 10 key papers from 1999-2014 explore mean-field theories and structural aspects (Parisi and Zamponi, 2010, 684 citations).

Key Challenges

Why It Matters

Jamming concepts explain rheology in industrial suspensions like paints, shampoos, and cements, where shear thickening enhances viscosity under stress (Wagner and Brady, 2009). They model biological tissues and soft body armor that stiffens on impact. Understanding jamming aids granular flow design and colloidal processing (Liu and Nagel, 2010; Seto et al., 2013).

Key Research Challenges

Critical Scaling Laws

Determining universal exponents for viscosity and elasticity near jamming remains unresolved across dimensions (O’Hern et al., 2003). Simulations struggle with finite-size effects obscuring true scaling. Experimental validation in soft materials is limited by polydispersity (Liu and Nagel, 2010).

Shear Jamming Mechanisms

Linking discontinuous shear thickening to friction and hydrodynamics challenges numerical models (Seto et al., 2013, 661 citations). Reproducing DST in simulations requires accurate granular interactions. Flow-induced structures complicate predictions (Vermant and Solomon, 2005).

Random Close Packing Density

Defining precise RCP in polydisperse systems versus mean-field predictions is contentious (Parisi and Zamponi, 2010). Asymmetric mixtures alter phase diagrams (Dijkstra et al., 1999). Fractal energy landscapes add complexity (Charbonneau et al., 2014).
