Bridges are regarded as one of the most important components transportation infrastructure. More and more repairs, inspections, alterations, construction processes required to maintain safe usage due increasing travel demands in addition bridge infrastructure aging. In this paper, we will discuss experimental investigation using five reinforced concrete beams evaluate effect making damage under...

An anisotropic damage model is employed in order to simulate the fracture pattern of Bohus granite under quasi-static (Q-S) spherical indentation loading. The chosen description added previously Drucker–Prager (DP) plasticity with variable dilation angle. resulting constitutive implemented behavior up load capacity material. initial fragmentation, corresponding first small load-drop force–penet...

The aim of this paper is to investigate the energy absorption behavior some reticulated tubes with different auxetic and non-auxetic wall grid patterns. Re-entrant, arrow-head anti-tetrachiral were three types cellular patterns for tubes, conventional honeycomb pattern was used tubes. All designed specimens fabricated by laser rotary cutting machine on steel crushing tests performed a universal...
