In this paper, a trilinear cohesive zone modeling approach available in the explicit nonlinear
finite element software LS-DYNA is used to model the dynamic impact failure of an adhesive …

This paper investigates the energy absorption and deformation characteristics of sandwich
structures with auxetic tetrachiral core under high velocity projectile impact. The finite …

Hail impact on structures such as building envelopes and vehicles can cause huge
economic loss every year. Numerical simulation of the hail impact process is crucial for the …

The inspection of airframes and aerodynamic surfaces is a very important task in
aeronautical maintenance. Traditionally, this labor has always been carried out by …

The most attractive aspect of metal foams is that they can combine the properties of metallic
materials (eg, strength, high melting temperature) with the properties of porous materials …

The concept of structural health monitoring has been introduced to ensure structural integrity
during the design lifetime of a structure. The main objectives of structural health monitoring …

Lattice sandwich structures have the advantage of high strength-to-weight and stiffness-to-
weight ratios. The laminated structures filled with viscoelastic materials have active and …

Aviation structures are required to be resistant to impact damage from hail. Therefore,
aiming to gain a better understanding of such impacts, the formation mechanisms …

Hail in nature is stronger than pure ice, and cotton fibers are usually added to imitate the
mechanical properties of hail in nature. In this paper, distilled water and absorbent cotton …

Hails impact on asphalt shingles causes huge economic losses every year. Numerical
simulation of the hail impact process is essential for mitigation strategy development. In this …
