Fracture-strain of Asphalt at Low Temperature.
Journal of The Japan Petroleum Institute, 1992 本研究は低温領域におけるアスファルトの破壊ひずみの値および破壊ひずみが温度, 載荷速度等によりどのように変動するか検討したものである。実験は著者らが新たに開発したもので, あらかじめひずみを測定した鋼板にアスファルトを塗布し, それをフラースぜい化点試験機に装着し一定温度で曲げ作用を与え, 様々な温度のアスファルトの破壊ひずみを求めるものである。実験により, 以下の結果を得た。温度が低下するに伴い破壊ひずみは減少し, 最小ひずみに漸近した。アスファルトの温度-破壊ひずみ曲線は, 載荷速度等の条件により温度軸方向に平向移動し, その形状はほぼ一定であると考えられる。また, 載荷速度を遅くした場合, その曲線は温度軸方向に平行移動した。

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.
