大鼠坐骨神經損傷后脊髓運動神經元捷狀神經營養因子的表達及針刺干預后的變化Based on biphasic porous medium model of articular cartilage, this thesis regards the solid phase as isotropic linear elastic medium, the fluid phase as ideal fluid, the deformation as small, and the permeability depending on the volume strain of solid phase, and deduce out the finite element method for this nonlinear model
本文針對關節軟骨兩相多孔介質模型，視固體相為各向同性線彈性介質，流體相為理想流體，變形為小變形，滲透率與固體相體積應變相關，研究該非線性模型的有限元法。Upon that an efficient thinning algorithm based on borderline ( etab ) is proposed which treats with individual pixels point in each step and picks up unilateral edge points sequence as the framework of a character image
演算法每一步都針對單個的像素點作處理，並提取筆劃單側邊緣點序列作為字元圖像骨架。In this procedure, a standard model of tibia and fibula was scaled and positioned according to the thickness of soft tissue at patellar tendon and fibular head, and then nodes and elements could be generated automatically according to the preference of user. soft tissues modulus in fe models was obtained with in - vivo measurement of the individual, the socket rectification was simulated by applying radial displacements to corresponding nodes
在有限元應力分析部分，本文建立了專門針對膝下假肢的有限元建模方法，包括自動骨定位和自動網格劃分，建模時對前人的模型做了優化，考慮了骨和軟組織材料的影響，同時也滿足了臨床使用的快捷、方便的要求。A good model of the full - grade aggregate concrete with high aggregate content is precondition to successfully execute concrete meso - mechanical simulation, so that the main work in the dissertation is focused on the following study concerning the random aggregate model of dam fully - graded concrete : ( 1 ) based on the topology of spherical aggregates, an algorithm of the random convex polyhedron aggregate model was presented considering the actual aggregate content, grading, and aggregate shape, and corresponding fortran program was developed to generate random convex polyhedron aggregate
針對全級配大壩混凝土的實際骨料含量和骨料形態，本文做了以下主要工作: （ 1 ）在一種高效率生成的隨機球骨料模型的基礎上，形成隨機凸多面體骨料模型，同時研究了細觀單元屬性判別方法，編制了對含有凸多面體骨料的細觀區域進行結構性有限元網格剖分程序。本文給出的三維隨機骨料模型演算法不但考慮了混凝土的骨料的實際級配和含量，而且計及了骨料的實際形態。Afterward the numerical method was used to decompose the inherited integration, so the matrix form of constitution equations was derived. then through utilizing the lagrange equation directly, the paper gets the finite element formula. to test the model, the paper calculate the osteoblast ' s dynamic response under near static load and sinusoidal load at a simple tension beam and a four point bending beam
針對單向拉伸和四點彎曲兩種離體培養成骨細胞的裝置，再根據實際情況，將培養基看成是一種多孔材料，而將成骨細胞看成是粘彈性體，利用自編的有限元分析程序分別計算了受擬靜態載荷和受交變載荷下細胞的動力響應，結果很好地反映了細胞的粘彈性性質。分享友人
