  1. 1. Plastic deformation of hot riveted joints acting in shear

    University essay from KTH/Bro- och stålbyggnad

    Author : Victor Gard; [2023]
    Keywords : ;

    Abstract : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. READ MORE

  3. 2. Numerical analysis of a bearing strength in delaminated composite joint

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Olavi Kukkonen; [2023]
    Keywords : Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Abstract : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

  4. 3. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    University essay from KTH/Lättkonstruktioner

    Author : Mara Santaniello; [2020]
    Keywords : ;

    Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

  5. 4. Virtual testing of self-piercing rivet connections

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Daniel Andersson; Fredrik Saliba; [2020]
    Keywords : FEM; SPR; self-piercing rivets; self piercing rivets; LS-dyna; Explicit FEM; lap-shear; cross-tension; KS2; r-adaptivity; 2D axisymmetric; axisymmetric;

    Abstract : The automotive industry is currently trying to replace the conventional steels to lightweight materials such as aluminum or carbon fiber to meet all stricter emission targets. When using such materials, traditional joining methods, such as spot welds, could be difficult to use. Therefore, more focus has been put on self-piercing rivets (SPR). READ MORE

  6. 5. Design of bi-adhesive joint for optimal strength

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Siva Koti Reddy Vennapusa; [2019]
    Keywords : Bi-adhesive joint; Linear elastic fracture mechanics; Cohesive zone modelling; Optimization;

    Abstract : To support the trust in the design development of adhesively bonded joints, it is important to precisely predict their mechanical failure load. A numerical simulation model with a two-dimensional linear elastic cohesive zone model using a combination of a soft and a stiff adhesive is developed to optimize the strength of a lap-joint.
