This chapter considers the deformation and strength of spherical particles of hydrogel materials—materials composed of sparse polymer networks containing large volume fractions of water. The mechanical behavior of particles of such materials is marked by significant compliance and large, non‐linear deformations. The axial and transverse deformation characteristics of spherical hydrogel particles in diametral compression are detailed and compared to those of structurally similar elastomeric rubber spheres. Experimental measurements show that both hydrogel and rubber spheres are characterized by constant volume deformation in diametral compression. The strengths of hydrogel particles are shown to be deformation rate dependent and are analyzed by deterministic extreme value effects, in this case controlled by testing rate not particle size.
