FEM Analysis of Anti-Mining Protection of Armored Vehicles

Abstract

The safety of the troop in an armored vehicle is paramount. The most serious threat to armored vehicles is a buried charge explosion or an improvised explosive device. The use of numerical approaches in the validation of armored vehicles minimizes the number of prototypes needed and speeds up the design process. This research focuses on blast simulation utilizing the ConWep (which stands for conventional weapon) method for STRENX armor steel used for blast protection in ALM (which stands for antilandmine) vehicles. The plate is modeled as a deformable solid with the Johnson-Cook plasticity model. In this paper protective plates were examined in order to determine which geometry gives the best protective conditions for the troop in an armored vehicle. Three different geometries were numerically tested, and two of them represent combined geometry. The maximal value of the plastic strain and maximal value of the vertical displacement of the central node on the protective plate was chosen as the parameters to represent the obtained results.

Costs of (re)designing the organizational structure in order to improve the competitiveness of transport companies

“…Takođe, zahtev za produženjem radnog vremena stanice direktno utiče na broj izvršilaca. Ispunjenje kriterijuma koji se tiču servisa i remonta (Pešić et al, 2022;Janjić et al, 2015), fizičkog obezbeđenja, pružanja usluga turističke agencije i slično direktno utiču na dizajniranje nove organizacione strukture. Svakako prethodno rečenom, treba dodati da svaka promena organizacije, pa makar to bila i samo u promeni broja zaposlenih, povećava verovatnoću da će da dođe do raskida ili uspostavljanja novih formalnih i neformalnih odnosa, što utiče na kvalitet organizacione klime i kulture, a time i na konkurentnost preduzeća preko postignuća zaposlenih na radnom mestu.…”
