  1. 1. Method Development & Analysis of Seals using FEM

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lovisa Svanborg Östlin; [2023]
    Nyckelord :FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Sammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER

  3. 2. Bibliometriska indikatorer som medskapare av verkligheten : Hur prestationsbaserade utvärderingssystem inverkar på samhällsvetenskapliga forskningspraktiker och vetenskapliga kommunikation

    Master-uppsats, Lunds universitet/Avdelningen för ABM, digitala kulturer samt förlags- och bokmarknadskunskap

    Författare :Johanna Tallefors; [2023]
    Nyckelord :Library and information studies; Research evaluation; Bibliometrics; Social Sciences; Research practices; Research Quality; Publication patterns; Disciplinary norms; Constitutive effects; Performance-based research funding; Academic Profession; Recruitment Processes; Candidate Evaluation; Peer Review; Cultural Sciences;

    Sammanfattning : The scope of this master thesis is the scientific publishing in Social Science at Lund University. By combining bibliometric studies and qualitative interviews, this thesis investigates how scholars in Social Sciences at Lund University respond to performance- based evaluation. LÄS MER

  4. 3. Practitioners of Social Investment Funds – Applied Phronesis : A study of how social investment fund policy framework affect the practices of professionals

    Master-uppsats, Södertörns högskola/Sociologi

    Författare :Hannes Kärrman; [2022]
    Nyckelord :Social Investments; Evidence-Based Policy and Practice; Phronesis; Relational Theory; Impact Evaluation; Constitutive Effects; sociala investeringar; evidensbaserad policy och praktik; Phronesis; relationell teori; effektutvärdering; konstitutiva effekter;

    Sammanfattning : Social Investments (SI) have become a significant policy tool during the 2010s for developing and implementing social policy. This study explores how the SI framework, based on social innovation, evidence-based policy and practice, and impact evaluation, affects professionals when it is implemented and evaluated. LÄS MER

  5. 4. Validation of An Iteration Free Material Model for Paperboard (NEO)

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Samuel Thomas Staines; [2022]
    Nyckelord :Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Sammanfattning : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. LÄS MER

  7. 5. Shear Failure of Steel Fiber and Bar Reinforced Concrete Beams Without Stirrups : Predictions based on Nonlinear Finite Element Analyses

    Master-uppsats, KTH/Betongbyggnad

    Författare :David Andersson; [2022]
    Nyckelord :Nonlinear finite element analysis; Shear failure; Fiber reinforced concrete beams; ATENA;

    Sammanfattning : Shear failure in concrete beams are often brittle in nature and potentially dangerous without adequatereinforcing measures. In design of concrete, it is commonly recommended to install transversalreinforcement along the shear span to induce a more ductile structural response, improving the shearcapacity all together and providing sufficient warning prior to collapse.
