Abstract
Modified strain regions are created in correlation to strain reactive structures that are subjected to a predetermined dimensional precision adjustment. The modified strain regions are created by impacting incident particles into exposed regions of the strain reactive structures. The irradiation by the incident particles creates a predetermined material disruption and consequently a change in strain energy. The strain energy, and the associated dimensional adjustment is dependent on the irradiation process and the sum properties of the modified strain regions and the strain reactive structure.
