“…The bullets stopped at 127 and 200 mm, depending on the riffle type and board surface material. The minimum commercial thickness walls are required to support 10 kg of sand per block [8]. Have to consider that the penetration depth is considerably larger in wet sand than in dry sand, independent of bullet type [9].…”

“…Several containers of glass fiber with different geometries have been used as an alternative to ballistic walls. The advantage of using fiber 2nd Materials Engineering and Modern Manufacturing (MeMM) materials is that they are cheap, environmentally friendly, and easy to repair compared to other ballistic blocks based on ceramics and plastics, which cannot be repaired after damage [8].

Human security remains a topical issue, especially on the country borders where temporary houses are often used. Optimally, people should be provided with ordinary, habitable, easy-to-build, possibly portable buildings and ballistically protected. However, there is a lack of studies addressing ballistic building materials for the walls. In the scope of this study, ten ballistic materials: sand walls, concrete, steel plates, ceramic, glass fibreboards, wood (plywood, cross-laminated timber), ultra-high molecular weight polyethylene (UHMWPE) boards, aramid boards, carbon fibre boards, and gypsum plasterboard are reviewed, and their wall constructions are compared. This paper aimed to analyse bulletproof materials and to nominate the best bulletproof walls according to three required aspects - price, thermal transmittance, and weight. This is a review article that could help stakeholders to choose the appropriate ballistic material for high-risk applications.

Белорусский государственный технологический университет 2 ЗАО «Струнные технологии» 3 Белорусский государственный университет РАЗРАБОТКА КОМПЬЮТЕРНОЙ МОДЕЛИ РАЗРУШЕНИЯ НЕОДНОРОДНОГО МАТЕРИАЛАВ представленной работе уделено внимание проблеме повышения эффективности моделирования процессов разрушения различных неоднородных материалов. В частности, основной акцент сделан на изучение процесса разрушения бетона. Представлены различные методики моделирования взаимодействия материалов с описанием их достоинств и недостатков. За основу в данной работе выбран метод Лагранжа, который, по мнению авторов, является наиболее подходящим. Использование предлагаемых в работе специальных компьютерных моделей в пакете инженерного анализа ANSYS/LS-DYNA позволяет решать с высокой степенью точности задачи прогнозирования процессов высокоскоростного разрушения сложных объектов. Использование метода Лагранжа позволяет снизить требования к вычислительному оборудованию и повысить точность расчетов за счет использования специального моделирования неоднородности среды. С целью подтверждения достоверности получаемых данных компьютерных моделей были проведены испытания на специальном полигоне, где бетонные образцы подвергались высокоскоростному воздействию со стороны снарядов (пуль). Проведенное исследование показало, что результаты численных экспериментов пулестойкости бетонных образцов с явным моделированием гранитного наполнителя приближены к результатам натурных испытаний, что подтверждает релевантность разработанных моделей и методики расчета. Полученные результаты позволяют получать достоверные результаты и при моделировании разрушения других неоднородных материалов, таких как древесина с различными дефектами.

Stress–strain and volume change behavior for clean sands which have distinct particle shape (rounded and angular) with very similar chemical (mineralogical) composition, size, and texture in one-dimensional (1D) compression and drained triaxial compression are presented. The effect of particle morphology on the crushing behavior in one-dimensional loading is explored using laser light diffraction technique which is suitable for particle crushing because of its high resolution and small specimen volume capability. Particle size distribution in both volume/mass and number distributions are considered for improved understanding associated with the process of comminution. Number distributions present a clearer picture of particle crushing. It is argued that particle crushing in granular assemblies initiates in larger particles, rather than in smaller particle. It was found that rounded sand specimens showed greater crushing than angular sand specimens with higher uniformity coefficient. In 1D compression, loose specimens compress approximately 10% more than dense specimens irrespective of particle shape. Densification of angular sand results in improvement in stiffness (approximately 40%) and is comparable to that of loose rounded sand. In general, density has a greater influence on the behavior of granular materials than particle morphology. The effect of particle shape was found to be greater in loose specimens than in dense specimens. The effect of grain shape on critical state friction angle is also quantified.
