The Grid-Characteristic numerical Method (GCM) that is quite common in solving aero and hydrodynamic problems can also be applied for mechanics of solids. It allows to implement complex border contact conditions, including the non-reflecting destructible contact. Both this conditions are very important precise effective modeling Low-Velocity Impacts (LVI) on fiber Fiber-Metal Laminates (FML) resulting Barely Visible Impact Damage (BVID) influences residual strength a composite aircraft part....
Abstract This work is the numerical study of age-dependent responses vascular system under low-mass high-speed impact scenario. The grid-characteristic method on adaptive mesh model human thorax tool study. Due to lack valid injury criteria, only provides information risk. simulation demonstrates that an older age changes significantly response and increases risk aorta injury. We focused because its rupture general consequence vehicle accidents (great mass impacts at relatively low...

Low-velocity strikes are considered as one of the most dangerous load types for composites, especially in aviation. They do not lead to an immediate destruction a whole detail, but inner damage, provoking delamination between layers or fiber and matrix, lowers material strength may cause during flight. This damage can only be noticed via complex study, which increases exploitation cost. Numerical modeling help interpret results obtained from common portable devices, currently used metals....
Abstract Correct diagnostics of vascular pathologies underlies treatment success for patients with cerebrovascular diseases. Transcranial ultrasound is the well-known method diagnostic Despite high sensitivity and specificity method, transcranial has some limitations related to B-mode image quality accurate insonation vessels interest. Overcoming these enables enhance procedure. The present work addresses numerical simulation propagation in a human head by grid-characteristic method. We used...
Abstract The paper is devoted to verification of previously proposed technique medical ultrasound modelling [
Abstract Transcranial ultrasound examination is hampered by the skull which acts as an irregular aberrator of signal. Numerical recovery field can help in elimination aberrations induced skull. In this paper, we address simulation medical phantom scanning through silicon aberrators with wave notching. The numerical model based on 2D acoustic equations are solved wavefront construction raytracing method. B-scan images compared experimental images.
Modeling of ultrasonic pulse in a medium is usually based on the system equations acoustics. This approximation means that, when wave pattern considered, only longitudinal waves are taken into account. approach works well many practically meaningful applications. However, for some cases consideration not enough, and an analysis complete elastic required. paper devoted to modeling formation using elasticity instead A transducer with phased array considered. Grid-characteristic numerical...
