Measurements of plastic strain around indentations caused by the impact of round and angular particles, and the origin of erosion

Mechanical properties and adhesion of oxide films examined by a solid particle impact method at high temperature corrosive environments

“…4 × 10 −3 corresponds to 30% of surface strain, which is roughly obtained as the nearly same indentation ratio in the previous paper [14], the surface strain at given ba −1 is roughly estimated from the constant value of ba −1 in Fig. 9, and aD −1 and dD −1 (b is equal to d) in Fig.…”

Practical estimation of erosion damage caused by solid particle impact

“…In fact, it has been confirmed that g(α) is a useful term, which reflects complicated erosion mechanisms as a function of the type of material [6]. This concept is supported by measurements of plastic strain around indentations [7]. It is well known that erosion damage is related to impact velocity v (m s −1 ), particle diameter D (m), and material hardness within a small range of hardness values or the same compositional systems.…”

Damage behaviour of metallic materials caused by subsonic to hypervelocity particle impact

“…The weight loss of metals by single particle impact cannot occur at deeper angles such as 80 or 90 degrees [10]. The impact velocity at the transition between Type I and II was below the sonic velocity for aluminium, but for the other target materials above the sonic velocity.…”
