Shear strain

In the present paper, by using the higher-order shear deformation theory and the strain-displacement relationships of large deflection, the postbuckling analysis of the functionally graded graphene-reinforced composite laminated (FG-GRCL) parabola, sinusoidal, and cylindrical externally pressured panels is presented in detail.

This research employs a novel third-order shear deformation theory to investigate the static buckling and static bending behaviors of organic nanoplates, marking the first instance of such an approach being used. The formulas are computed using strain gradient theory to consider the impact of the size effect, where this size effect parameter is considered in both positive and negative cases.

In this study, a series of Consolidated–Undrained triaxial compression tests were conducted at a constant axial strain rate, with a small unloading and reloading during the monotonic loading to investigate the effect of various densities and curing times on the mechanical properties of Liquefied Stabilized Soil (LSS).

This paper presents the free vibration and critical buckling analyses of porous plates based on the first-order shear deformation theory by the proposed three-node triangular element. The bending strain fields of the suggested element are enriched by the bubble node located at the centroid of the triangular element.

In this paper, the severe plastic deformation method (SPD) known as constrained groove pressing (CGP) was applied to produce ultrafine-grained microstructure in IF steel sheets. In the CGP technique, samples are subjected to repetitive shear deformation under the plane strain deformation condition using the constrained grooved and flat dies.

This paper presents a numerical solution for vibration analysis of cantilevered non-uniform trapezoidal thick plates. Based on the first shear deformation theory, kinetic and strain energies of the plate are derived and using Hamilton's principle, governing equations and boundary conditions are derived.

Different criteria are available in the literature to assess the fracture behaviour of sharp V-notches. A typical and well-known criterion is based on the application of the notch stress intensity factors (NSIFs), which are able to quantify the intensity of the stress fields ahead of the notch tip.

U vú là bệnh lý thường gặp ở phụ nữ. U vú lành tính chiếm 80%, ác tính chiếm 20%. Ung thư vú gây tử vong hàng đầu ở phụ nữ, trong đó có Việt Nam. Siêu âm đàn hồi mô ra đời, đánh giá độ cứng của mô, giúp phân biệt khối u mềm hay cứng, từ đó có thể giúp phân biệt lành tính hay ác tính. Có hai loại siêu âm đàn hồi mô là siêu âm đàn hồi mô sức căng bề mặt SE (Strain Elastography) và siêu âm đàn hồi sóng biến dạng SWE (Shear Ware Elastography).
