...M. A. Dawson; G. H. McKinley; L. J. Gibson The response of a reticulated, elastomeric foam filled with colloidal silica under dynamic compression is studied. Under compression beyond local strain rates on the order of 1 s − 1 , the non-Newtonian, colloidal silica-based fluid undergoes dramatic...

...Zdeněk Bažant; Peter Grassl Because the observed size effect follows neither the strength theory nor the linear elastic fracture mechanics, the delamination fracture of laminate-foam sandwiches under uniform bending moment is treated by the cohesive crack model. Both two-dimensional geometrically...

...N. P. Kruyt The shear modulus of two-dimensional liquid foams in the dry limit of low liquid content has been studied theoretically. The focus is on the effect of geometrical disorder on the shear modulus (besides the influence of surface tension). Various theoretical predictions are formulated...

...G. J. McShane; V. S. Deshpande; N. A. Fleck The finite element method is used to evaluate the underwater blast resistance of monolithic beams and sandwich beams containing prismatic lattice cores (Y-frame and corrugated core) and an ideal foam core. Calculations are performed on both free-standing...

...Lixin Gong; Stelios Kyriakides The compressive response of many foams is characterized by an initial linearly elastic regime which is terminated by instability. For open cell foams instability leads to localized buckling and collapse of zones of cells. Local collapse in these zones is terminated...

...T. Wierzbicki; M. Doyoyo A new specimen for determining the local stress-strain response of foams under uniaxial compression is presented along with the corresponding theory. The drawback of using conventional cubic specimens is that average stresses and strains are calculated, which introduces...

..., a sensitive transmission bar is required to detect the weak transmitted pulses. Experimental results show that homogeneous deformations at nearly constant strain rates can be achieved in materials with very low impedances, such as a silicone rubber and a polyurethane foam, with the experimental modifications...

...S. Jemiolo; S. Turteltaub, Assoc. Mem. ASME, A parametric model for foam-like materials is proposed and its correlation with experimental results is analyzed. The class of foam-like materials is assumed to be described by an isotropic elastic potential based on a general model proposed by Ogden...
