工程實務中若有物體之間的接觸就會衍生一些問題，例如表面的磨秏、破壞等。有時工程實務中因功能上的需要而必須預先留下孔洞，例如道路上內埋管線或建築物內埋之水管、電線管路等等，在受力狀態下，因孔洞或縫隙存在所產生的應力集中現象而易於發生破壞。本研究最主要的目的就是在探討含孔缺陷之構件於接觸負載下所產生的應力分佈狀況。
本研究為利用穿透式數位光彈法，配合影像處理程式以探討含近邊界圓孔平板在其邊界上承受集中負荷之應力分佈。本研究特別提出了有別於一般疊加理論之疊加法，將已知的修正接觸理論之應力分佈來取代受拉伸負載含圓孔無窮平板解之施力項s0並再疊加上修正接觸解後，獲得含近邊界圓孔平板接觸理論解，在此特稱此種方法為取代式疊加法(Replaced Superposition Method)。並利用光彈取點程式配合疊代程式和倒畫光彈影像程式倒畫出理論之光彈條紋圖形，再以細線化程式將理論倒畫所得之影像細線化，再疊加上實驗影像加以比較以判斷理論之正確性。其次，再改變施力點位置及圓孔中心離邊界距離以了解應力分佈之改變。
