“…When the load is increased, indentation pile-ups progressively vanish around the indent site yielding loss of geometric similarity. Thereafter, the infinite half-space assumption commonly used in indentation mechanics needs to be reconsidered [6]. A model for plastic punching was proposed for the {111}A and B orientations of specimens where plastic flow occurs in three diamond-shaped columns.…”

“…Unfortunately, instrumented nanoindentation at elevated temperature is very difficult to perform [3] and most studies have been undertaken at room temperature (RT). Furthermore, contact mechanics has been developed for semi-infinite half-space models [4], an assumption that is not appropriate when the size of the plastic zone approaches one of the dimensions of the object [5,6]. Thin self-standing structures are expected to show mechanical behaviour quite different from that of bulk samples.…”

“…5 Size effect Contact mechanics has been developed for semi-infinite half space [20], this assumption being not fulfilled when the size of the plastic zone becomes of the order of one of the dimensions of the object and then size effects are expected [27][28][29]. For instance, thin structures are expected to show a mechanical behaviour quite different from that of a bulk.…”

“…For instance, thin structures are expected to show a mechanical behaviour quite different from that of a bulk. In the field of semiconductors recent studies showed that indeed, when the contact depth to thickness ratio h c / t approaches 3 %, a free standing film cannot be considered as a semi-infinite half space anymore and plastic deformation of the free bottom side is to be taken into account [28]. These length-scale effects may have important implication in the growing of mismatched layers for optoelectronic devices [9].…”
