Šavija, B. (author), Smith, G.E. (author), Liu, D (author), Schlangen, E. (author), Flewitt, P.E.J. (author)Deformation and fracture of materials are usually considered in terms of brittle and ductile modes. However, there is an intermediate class between these limits that is termed quasi-brittle where there is measurable inelastic deformation prior to final graceful ‘brittle’ failure. In previous work, we presented deformation and fracture data...journal article 2018

Liu, D (author), Šavija, B. (author), Smith, G.E. (author), Flewitt, P.E.J. (author), Lowe, T. (author), Schlangen, E. (author)In this work, porosity-property relationships of quasi-brittle materials are explored through a combined experimental and numerical approach. In the experimental part, hemihyrate gypsum plaster powder (CaSO 4 ⋅1/2H 2 O CaSO4⋅1/2H2O) and expanded spherical polystyrene beads (1.5–2.0 mm dia.) have been mixed to form a model material with...journal article 2017
