Comparison between flexural and uniaxial compression tests to measure the elastic modulus of silica aerogel

Preparation and characterization of monolithic alumina aerogels

“…The modulus of alumina aerogel is more than 2.5 times that of silica aerogels with the similar density (The compressive modulus of the silica aerogel with the density of 0.18 g/cm 3 is about 3.88 MPa reported by A.H. Alaoui et al) [24]. The increased strength of the alumina aerogel is probably attributed to its crystalline structure and interconnected fibrous morphology.…”

Process, structure and texture of extruded whole wheat

“…The rupture stress s * and elastic modulus E * of the extruded samples were derived from the maximum force at rupture F and the slope of the linear part of the force (F) vs. crosshead displacement (d) curves, respectively. The stress at rupture and elastic modulus were then calculated according to equations (9) and (10) (7 repeats) (Alaoui et al, 2008):…”

Effect of wheat bran on the mechanical properties of extruded starchy foams

“…For the cylindrical extruded samples (index *), the stress at rupture and elastic modulus were calculated according to Eqs. (3) and (4) (10 repeats) (Alaoui, Woignier, Scherer, & Phalippou, 2008):…”
