  1. 6. Numerical modeling and experimental investigation of large deformation under static and dynamic loading

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Benjamin Bondsman; [2021]
    Nyckelord :Total Lagrangian; Updated Lagrangian; Newmark; Energy Conserving; Algorithm; Numerical; Modeling; Large; Deformation; steel; Wood; Pine; Plane Strain; 3D;

    Sammanfattning : Small kinematics assumption in classical engineering has been in the center of consideration in structural analysis for decennaries. In the recent years the interest for sustainable and optimized structures, lightweight structures and new materials has grown rapidly as a consequence of desire to archive economical sustainability.

  3. 7. Finite Element Modeling of Short, Randomized Fiber Composite Material

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Simone Ambrogio; [2020]
    Nyckelord :;

    Sammanfattning : With the advent of hybrids and electric vehicles, the need for lightweight and highperformancematerials is growing. Sheet molding compound (SMC) is a compositemade of short and randomized  bers that o ers a substantial weight reduction andgood mechanical properties while meeting the demand for large volume production.

  4. 8. Three-dimensional constitutive finite element modeling of the Achilles tendon

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Giacomo Longo; [2015]
    Nyckelord :Constitutive modeling; FEM; Achilles tendon; Soft tissue; Fluid behaviour; 3D geometry; Technology and Engineering;

    Sammanfattning : Tendons connect muscles to bones enabling efficient locomotion. This study focuses on the Achilles tendon, which is the strongest tendon in the body and fundamental for activities like walking, running and jumping. The Achilles tendon is the most frequently subjected tendon when it comes to injuries and ruptures. LÄS MER

  5. 9. Biomechanics of Arterial Smooth Muscle. : - Analyzing vascular adaptation of large elastic arteries using in vitro experiments and 3D finite element modeling.

    Magister-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Susanne Lewin; [2014]
    Nyckelord :;

    Sammanfattning : A number of cardiovascular diseases (e.g. aortic aneurysm, aortic dissection and atherosclerosis) are associated with altered biomechanical properties in the vascular wall. This thesis studies vascular adaptation and its resulting alteration in biomechanical properties. LÄS MER

  7. 10. Assessment of Finite Element Softwares for Geotechnical Calculations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik

    Författare :Alex Spetz; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : When building new constructions under ground level in cities it is important that the foundations of neighboring buildings are undisturbed. The regulations regarding soil deformations are hence very strict and conventional methods of predicting soil behavior is often too crude. LÄS MER
