The paper presents the results of a study bifurcation axisymmetric equilibrium forms round plates under various conditions for fixing outer edge. It is shown that case sliding edge, analytical, asymptotic and finite element approaches give close results. When edge plate hinged, buckling to non-axisymmetric state occurs at much higher load with formation smaller number waves than boundary condit...

The Euler buckling theory states that the buckling critical strain is an inverse quadratic function of the length for a thin plate in the static compression process. However, the suitability of this theory in the dynamical process is unclear, so we perform molecular dynamics simulations to examine the applicability of the Euler buckling theory for the fast compression of the single-layer MoS2. ...

Acoustic behavior of lipid-coated microbubbles has been widely studied, which has led to several numerical microbubble dynamics models that incorporate lipid coating behavior, such as buckling and rupture. In this study we investigated the relationship between microbubble acoustic and lipid coating behavior on a nanosecond scale by using fluorescently labeled lipids. It is hypothesized that a l...

Many studies have measured the global compressive properties of tissue engineered (TE) cartilage grown on porous scaffolds. Such scaffolds are known to exhibit strain softening due to local buckling under loading. As matrix is deposited onto these scaffolds, the global compressive properties increase. However the relationship between the amount and distribution of matrix in the scaffold and loc...

The formed-in-place pipe (FIPP) is a trenchless technology used for pipeline rehabilitation. It folded PVC that expands through thermoforming to fit tightly inside the host pipe. However, deficiencies during construction of FIPP liners such as insufficient inflation, misalignment and initial deformation will lead elliptical liner, which affects load-bearing performance liner makes it susceptibl...
