The interest in the design and numerical modelling of adhesively-bonded components structures for industrial application is increasing as a research topic. Although on joint failure under pure mode widespread, applied bonded joints are often subjected to mixed loading at crack tip, which more complex than affects strength. Failure these objective predictions through mathematical models, latter ...

Strain-rate effects on fracture behavior of unidirectional composite materials are studied. Single-edge notched multi-layered unidirectional graphite composites (T800/3900-2) are investigated to examine fracture responses under static and dynamic loading conditions using a digital speckle correlation method. The fracture parameters for growing cracks are extracted as a function of fiber orienta...

The interface crack of a slab track is fracture mixed-mode that experiences complex loading–unloading–reloading process. A reasonable simulation the interaction between layers tracks key to studying crack. However, existing models disease have problems, such as stress oscillation tip and self-repairing, which do not simulate mixed mode cracks accurately. Aiming at these shortcomings, we propose...

A novel continuous heterogeneous crystallization process is developed in which the active pharmaceutical ingredient (API) is crystallized directly on the surface of an excipient within the crystallizer. The product is subsequently dried and formed into tablets without the need for complex downstream processing steps, such as milling, sieving, granulation, and blending. The aim is to eliminate m...

In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...

one of the main disadvantages of anaerobic wastewater treatment at a low ph is the significantoperational cost due to the addition of necessary alkali. to reduce alkali supplement and thus the cost, thisstudy proposes a sequential multi-feed (sqmf) mode (distributed feeding) and effluent recycle (er) mode.experiments were conducted with a pilot-scale (2.5 m3) thermophilic (55°c) multi-staged up...
