Advanced Engineering Materials, EarlyView.Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Theoretical Study of Shear Wrinkles in Web Span
JAPAN TAPPI JOURNAL, 2011 抄紙機や輪転機などの連続走行紙（巻取紙）の搬送において，紙要因によるシワのトラブルはその発生メカニズムが判然としないため対応に苦慮する場合が多い。そこで，シワがローラに乗り上げて折ジワにつながる前段階としての剪断ジワが，紙要因で発生する条件について，紙の走行性の観点からFEMを用いて理論的な考察を行った。その結果，配向角の傾きやテンションのプロファイルといった紙由来の要因により，走行紙の横移動を生じる可能性があることが判明した。これは，張力が負荷されることによって紙が駆動ローラ上で剪断変形し，その状態のまま摩擦搬送されることによって起こると考えられる。さらに，紙の張力と横移動によって生じた剪断ジワが，ローラ上に乗り上げて折ジワへと成長する過程を解析する手法についても検討を行った ...

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Test on 15m Span Composite Cellular Beam
, 2014 NoCellular beams are the preferred form of long span construction in multi-storey buildings. For efficient design of composite cellular beams, asymmetric sections are often manufactured in which the bottom flange is larger than the top flange.

Multi-frequency vortex-induced vibrations of a long tensioned beam in linear and exponential shear flows [PDF]
, 2013 The multi-frequency vortex-induced vibrations of a cylindrical tensioned beam of aspect ratio 200, free to move in the in-line and cross-flow directions within first a linearly and then an exponentially sheared current are investigated by means of direct

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
