### Dynamic X-ray radiography for the determination of foamed

Moreover, theoretical investigation based on the 3D X-ray computed tomography scan dataset of bubble merging showed that the disjoining pressure increased as the gap between the bubbles in the surface layer (foam film) decreased with time and finally was ruptured.

Notably, for cement-based materials, x-ray and neutron tomography lend themselves as highly complementary tools for the study of their THM behavior. In fact, the high sensitivity to density variations of x-ray imaging gives access to the developments of fractures, in 4D (3D+time). On the other hand, neutron tomography allows the study of the

### Aggregate Geometry Generation Method Using a Structured

Abstract Mesoscale numerical modeling is an effective method of representing concrete as a three-phase material. Accurate aggregate geometry representation is an important aspect in numerical mesoscale modeling of concrete to predict mechanical properties as well

GeoDict – The Digital Material Laboratory. The dependence of macroscopic material properties on the microscopic material geometry is emerging as a key aspect in many current material optimization applications. The influence of geometry on the property is omnipresent: from fiber orientation. the strut-thickness of sponges.

### Experimental and mesoscopic investigation of double-layer

Abstract This paper focuses on the mechanical response of double-layer aluminum foam under static and impact loading. In the first part, experimental investigations are conducted to research the static and dynamic response of aluminum foam. The mechanical response of single- and double-layer specimens is discussed. In the second part, a mesoscopic model is developed based on X-ray CT (computed

Authors: M.N. Ibrahim, Waluyo Adi Siswanto, Ahmad Mujahid Ahmad Zaidi. Abstract: In this paper a study is presented on the numerical analysis of the failure process of aluminium armour plate subjected to normal impact by hemispherical projectiles. The perforation process has been simulated by the application of 3D analysis using IMPACT dynamic
