Mechanical Engineering Journal, 2016 In s-version finite element method (s-FEM), a local mesh is superposed on a global mesh, and they are solved monolithically. The local mesh represents the local feature such as a hole, whereas the global mesh does the shape of a structure.

Chondro progenitor cell response to specifically modified substrate interfaces [PDF]
, 2010 Current visions in cartilage repair aim at moving from fibrocartilaginous to a more hyaline like repair tissue by combining autologous cells of different origins (in situ recruited or in vitro precultivated) with repair supporting biomaterials.

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Application of finite element methods to the post-buckling behaviour of thin plates containing imperfections [PDF]
, 1978 A finite element program, applicable to the pre- and post-buckling behaviour of plates with imperfections, is developed. Suitable incremental stiffness matrices are generated for a plate element with four nodes and twenty degrees of freedom ...

Elememt Stiffness Matrix of Members of Reticulated Shell with End Springs
, 2011 In this paper, a tangent stiffness matrix of members with end springs of reticulated shell is derived on the basis of Timoshenko’s beam-column theory. In this matrix, joint’s axial stiffness and bending stiffness are considering together, non-linear beam-

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Theoretical framework for DOUBLE-DOUBLE composite plates under bending loads
Acta Scientiarum: TechnologyThis paper provides an insightful comparative analysis of laminated composite plates, focusing on two main stacking sequence groups: the traditional QUAD and the more recent DOUBLE-DOUBLE (DD) proposed by Professor Stephen Tsai.

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Advanced Functional Materials, EarlyView.Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.
