DOI: 10.1088/1361-6404/ac221e
Abstract: The impact of a hard ball on a soft surface involves deformation of the surface, with consequent changes in the coefficient of restitution (COR) as the angle of incidence is varied. Experimental results are presented… read more here.

DOI: 10.3390/ma15030852
Abstract: Soft polymeric gels are susceptible to buckling-induced instabilities due to their great compliance to surface deformations. The instability patterns at soft interfaces have great potential in engineering functional materials with unique surface properties. In this… read more here.
