Young's modulus evolution with temperature of glass/andalusite model materials: Experimental and numerical approach

► Two-phase glass-andalusite samples have been prepared by cold uniaxial pressing. ► Interfacial contact is perfect and oriented cracks are located inside inclusions. ► Young's modulus vs. temperature depends on the size of andalusite aggregates. ► Numerical stress distribution is affected by anisotropic properties of inclusions. ► Numerical and experimental results in terms of Young's modulus are in good agreement.
