Investigation of fiber and cracking behavior for conventional and ultra-high performance concretes using x-ray computed tomography
… identified between mechanical performance and cracking parameters that could be quantified mathematically and implemented into future finite element analysis models. Second, these test results demonstrated that the cracking structures of UHPC samples subjected to the double punch test (DPT) are …

Einfluss von Aluminiumoxid- und Titanoxid-Additiven auf die Thermoschockbeständigkeit von MgO-teilstabilisiertem Zirkonoxid
… which generates internal stresses and finally a crack structure is formed that is superimposed on the existing basic porosity. The objective of this PhD dissertation is to investigate the thermal shock resistance of this group of materials as a function of the primary structure – through various …
