電子部品のはんだ接合部の断線寿命をシミュレーションのみで定量的に予測する修正累積損傷モデルを開発した。本手法は，筆者らが提案した累積損傷に基づく疲労き裂進展評価手法で課題であった算出寿命の要素寸法依存性を，HRR特異場理論から算出される補正係数を用いて，逐次補正することで解決したものである。従来の手法で必要であった実はんだ接合部での温度サイクル試験や機械的疲労試験は不要となるため，評価期間の大幅な …

… The lengths of the indentation cracks running near parallel to the interface were measured and the orientation of crack propagation was characterized. … The crack length and orientation were significantly affected by the distance from the interface and by the marginal angle, respectively. … The crack length extended as the distance from the interface was shortened. …

… We present an evaluation method of the crack growth rate and behavior for a semi-elliptical surface crack in a plate subjected to arbitrarily stress distribution. … Although the arbitrarily stress distribution such as weld residual stress on the crack surface are difficult to approximate by using a polynomial formula, the stress intensity factor could be calculated by direct mapping of arbitrary stress field obtained from doing finite element analysis of the crack surface. …

… In order to clarify the loading frequency effect on the Fatigue Crack Growth Rate in a low pressure hydrogen gas environment, fatigue crack growth tests were carried out on an A6061-T6 aluminum alloy at several loading frequency levels in pure dry hydrogen gas, in air and in pure dry nitrogen gas. … The main cause of the loading frequency effect is related to thermal activation in the plastic zone at the tip of a crack growing across the grains by slip-off. …
