Exact solution for a two-dimensional Lamb’s problem due to a strip impulse loadingActa Mechanica Solida Sinica - Tập 20 - Trang 258-265 - 2007
Guangyu Liu, Kaixin Liu
By applying the integral transform method and the inverse transformation
technique based upon the two types of integration, the present paper has
successfully obtained an exact algebraic solution for a two-dimensional Lamb’s
problem due to a strip impulse loading for the first time. With the algebraic
result, the excitation and propagation processes of stress waves, including the
longitudinal wave... hiện toàn bộ
Hybrid Meta-Model Based Design Space Differentiation Method for Expensive ProblemsActa Mechanica Solida Sinica - - 2016
Nianfei Gan, Guangyao Li, Jichao Gu
In this work, a hybrid meta-model based design space differentiation (HMDSD)
method is proposed for practical problems. In the proposed method, an
iteratively reduced promising region is constructed using the expensive points,
with two different search strategies respectively applied inside and outside the
promising region. Besides, the hybrid meta-model strategy applied in the search
process make... hiện toàn bộ
Local Bending of Thin Film on Viscous LayerActa Mechanica Solida Sinica - Tập 23 - Trang 106-114 - 2010
Yin Zhang, Yun Liu
Effects of deposition layer position and number/density on local bending of a
thin film are systematically investigated. Because the deposition layer
interacts with the thin film at the interface and there is an offset between the
thin film neutral surface and the interface, the deposition layer generates not
only axial stress but also bending moment. The bending moment induces an instant
out-of-p... hiện toàn bộ
Elastic SH Wave Propagation in Periodic Layered Composites with a Periodic Array of Interface CracksActa Mechanica Solida Sinica - - 2015
Zhizhong Yan, Chunqiu Wei, Chuanzeng Zhang
The interaction of anti-plane elastic SH waves with a periodic array of
interface cracks in a multi-layered periodic medium is analyzed in this paper. A
perfect periodic structure without interface cracks is first studied and the
transmission displacement coefficient is obtained based on the transfer matrix
method in conjunction with the Bloch-Floquet theorem. This is then generalized
to a single ... hiện toàn bộ
A Transversely Isotropic Magneto-Electro-Elastic Circular Kirchhoff Plate Model Incorporating Microstructure EffectActa Mechanica Solida Sinica - Tập 35 - Trang 185-197 - 2021
Wei Shen, Gongye Zhang, Shuitao Gu, Yu Cong
A non-classical model for transversely isotropic magneto-electro-elastic
circular Kirchhoff plates is established based on the extended modified couple
stress theory. The Gibbs-type variational principle is used to obtain the
governing equations and boundary conditions. To illustrate the newly derived
model, the static bending problem of a clamped circular plate subjected to a
uniformly distribute... hiện toàn bộ
