The main results and academic contributions of the dissertation can be summarized as following : 1 ) for the difficulty to obtain the accurate analytical solution of the stress constraints around 3d cracks, detailed 3d fe analyses have been conducted to study the out - of - plane constraint factor tz around a straight through - thickness crack, a quarter - elliptical corner crack and a semi - elliptical crack embedded in an isotropic elastic plate subjected to uniform remote tension loading. the distributions of tz are minutely studied in the forward section of the cracks. strong 3d zones ( tz > 0 ) along the crack front were investigated despite the far field stress - free boundary conditions
全文主要研究內容和學術貢獻如下: 1 .針對一般三維裂紋端部場應力約束準確解析的困難，對均勻拉伸載荷作用下各向同性彈性板中穿透厚度中心直裂紋、半橢圓表面裂紋和1 / 4橢圓角裂紋進行了大量詳細的全場應力三維有限元分析，首次全面分析了非穿透裂紋端部場三維影響區范圍，給出了不同形狀三維裂紋前沿離面應力約束因子tz的數值解，並結合k場平面解給出了非穿透裂紋端部應力場k - tz雙參數描述。For laminate containing penetrated crack, " two planes " model is introduced to analyze the influence of repair parameters on the strength of repaired laminate, including such as patch size, patch thickness, patch layout, the location of rivets
摘要針對含穿透性裂紋的損傷層壓板，採用「兩板」模型建立起機械連接修補結構有限元分析模型，分別計算補片大小、厚度、鋪排方式以及連接件位置等修補參數對修補效果的影響。Disc specimens have great application in testing the mechanic properties of rock, such as the cracked chevron notched brazilian disk ( ccnbd ) and the cracked straight - through brazilian disc ( cstbd ) used in testing rock fracture toughness, the brazilian disc and the flatted brazilian disc ( fbd ) used in testing rock tensile strength
圓盤類試樣在巖石的力學性質測試中有著廣泛的應用。如應用於巖石斷裂韌度測試的人字型切槽巴西圓盤（ ccnbd ） ，中心穿透直裂紋巴西圓盤（ cstbd ） ，應用於巖石抗拉強度測試中的巴西圓盤試樣和平臺巴西圓盤（ fbd ）等試樣。
