Comparison of fatigue performance of polyethylene pipe grades in the form of extruded and compression molded specimens
(Elsevier, 2023-01-13)Due to the very long operational lifetimes (up to 100 years) of polyethylene pipes, there is a strong demand for accelerated testing of pipe materials to experimentally prove the ability of a certain material to achieve ... -
Fatigue behavior of DIN 1.4307 and DIN 1.4306 stainless steels under high frequency loading
(Elsevier, 2023-01-13)Two stainless steels DIN 1.4307 and DIN 1.4306 were tested by an ultrasonic fatigue loading device under push-pull mode (stress ratio R=-1). Life-time curves were determined in the high and very high cycle fatigue regions. ... -
Physico-Chemical Properties of Lithium Silicates Related to Their Utilization for Concrete Densifiers
(MDPI, 2023-03-08)Protection of concrete against aggressive influences from the surrounding environment becomes an important step to increase its durability. Today, alkali silicate solutions are advantageously used as pore-blocking treatments ... -
