Abstract: Masonry arches are usually composed of individual blocks or voussoirs, which are highly discontinuous and nonlinear, and it is extremely difficult or even impossible to simulate their collapse behavior using finite element methods. Therefore, a… read more here.

DOI: 10.1063/5.0270195
Abstract: Fault zones containing fluids such as water, gas, or oil exhibit reduced mechanical stability, making them more prone to reactivation and slip. Understanding how stress redistributes during slip is essential for assessing fault-related risks in… read more here.

DOI: 10.3390/math13203259
Abstract: This paper investigates D-finite discrete generating series and their sections. The concept of D-finiteness is extended to multidimensional discrete generating series and its equivalence to p-recursive sequences is rigorously established. It is further shown that… read more here.
