Dynamic Cracks vs. Statics Cracks: Effects and Repair ...

Dynamic crack is a term used to describe the growing process of cracks in concrete structures due to rapidly occurring forces like changing loads imposed on the structure. Static cracks can be eyesores and allow water penetration, whereas dynamic cracks compromise the structure's integrity. Static cracks may turn to dynamic cracks if they ...

Effect of rubber aggregate size on static and dynamic ...

Rubberized concrete specimens were prepared with different maximum rubber aggregate sizes ranging from 1 to 3 mm to 3 to 5 mm while the rubber content was kept constant at 15% by volume. The dynamic compressive behavior of rubberized concrete was investigated by using split Hopkinson pressure bar (SHPB) tests.

Peridynamic modeling and simulations on concrete …

In this paper, we simulate the dynamic fracture and failure of three-dimensional concrete structures using the peridynamic theory. Considering the heterogeneities and mesoscopic characteristics of concrete material, the dynamic failure of concrete is investigated by employing an intermediately homogenized peridynamic (IH-PD) model, in which information from the …

Assessing Viscoelastic Properties of Concrete during its ...

This paper aims to demonstrate the feasibility of a recently proposed approach (termed VisCoDyn) to assess the viscoelastic behaviour of concrete from the earliest ages, by introducing a known dynamic excitation to a simply supported specimen. The method involves the continuous monitoring of the response of the tested sample in terms of amplitude (force and …

Measurement of KLa

Measurement of KLa. It is extremely difficult to measure both 'K L ' and 'a' in a fermentation and, therefore, the two terms are generally combined in the term K L a, know as the volumetric mass-transfer coefficient, . The units of . K. L. a, are reciprocal time (h-1). The volumetric mass-transfer coefficient is used as a measure of the aeration capacity of a fermenter.
