  1. 1. A Deep-Learning-Based Approach for Stiffness Estimation of Deformable Objects

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nan Yang; [2022]
    Keywords : Robotic grasping; Deformable objects; Deformation modeling; Stiffness estimation; Deep learning; Robotgrepp; Deformerbara föremål; Deformationsmodellering; Styvhetsuppskattning; Djup lärning;

    Abstract : Object deformation is an essential factor for the robot to manipulate the object, as the deformation impacts the grasping of the deformable object either positively or negatively. One of the most challenging problems with deformable objects is estimating the stiffness parameters such as Young’s modulus and Poisson’s ratio. READ MORE

  3. 2. Towards the measurement of two independent viscoelastic functions using spherical indentation

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Hassan Mohammad; [2016]
    Keywords : ;

    Abstract : Instrumented indentation is a promising testing technique for obtaining the time dependent viscoelastic properties of bitumen and bitumen-based mastics. It offers several advantages: controlling the length scale of measurement and thus could be used in multi-scale modelling of asphalt, the possibility of in-situ tests and the minimal requirements of sample preparation.

  4. 3. Testing and modelling of UHMWPE.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Linus Gediminas; [2014]
    Keywords : ;

    Abstract : The mechanical behavior of unidirectional Dyneema fiber composite is an interesting topic. It is an unusual material composed by basically fiber and glue. The material has a simple makeup but complex behavior. This needs to be studied in order to understand and calculate the mechanical properties. READ MORE

  5. 4. Capacity assessment of a single span arch bridge with backfill : A case study of the Glomman Bridge

    University essay from KTH/Byggvetenskap

    Author : Henrik Bjurström; Johan Lasell; [2009]
    Keywords : Arch bridge; vault; finite element; backfill; failure envelope; masonry; capacity assessment; Bågbro; valv; finita element; fyllning; brottenvelopp; stenvalv; klassningsberäkning;

    Abstract :   The aim of this Master Thesis is to assess the load carrying capacity of the Glomman Bridge outside of the Swedish city Örebro. The Glomman Bridge is an unreinforced concrete single span arch bridge with backfill. The bridge was constructed in 1923 on assignment from the Swedish National Railways (SJ). READ MORE
