  1. 31. Material parameter identification of a thermoplastic using full-field calibration

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Nikhil Prabhu; [2020]
    Keywords : DIC; FFC; Thermoplastics; Material parameter identification; multi-point history; Polyamide 6; GISSMO; Response Surface Methodology;

    Abstract : Finite element simulation of thermoplastic components is gaining importance as the companies aim to avoid overdesign of the components. Cost of the component can be minimized by using an adequate amount of material for its application. READ MORE

  3. 32. Modeling and Evaluation of a Finite Element Cervical Spinal Cord for Injury Assessment

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Nicole Valle Olivera; [2020]
    Keywords : Biomechanics; Neuronics; Spinal Cord; LS-Dyna;

    Abstract : Motor vehicles collisions and falls have gradually increase the risk for spinal cord injuries. An increased knowledge of the spinal behavior and its injury mechanisms can be used as preventive strategies. READ MORE

  4. 33. 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

  5. 34. Development of a new test methodology for car-to-truck crash

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Matas Buzys; Sara Nilsson; [2019]
    Keywords : Crash tests; FUP; Frontal impact; Honeycomb structure; FUP; Frontalkrock; Honeycomb struktur; Kraschtest;

    Abstract : Till följ av de stora skadorna som riskeras vid frontalkollision mellan personbil och lastbil, utför Scania CV AB kraschtester för att bättre kunna utveckla komponenter med syfte att skydda passagerarna i personbilen. Den typ av test som denna studie bygger på utvärderar den s.k. FUP:en (engelska Front Underrun Protection). READ MORE

  6. 35. CAE modelling of cast aluminium in automotive structures

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Subrat Singh; Sreehari Veditherakal Shreedhara; [2019]
    Keywords : Material failure model; LS- Dyna; Non-linear Finite Element analysis; Cast aluminium; Explicit FEA; LS-DYNA; Drop tower; Spring tower; Strut Tower; FEM; CrachFEM; ANSA;

    Abstract : In the automobile industry, there is a big push for the automotive car manufacturers to base engineering decisions on the results of Computer Aided Engineering (CAE) solutions, and to transform the prototyping and testing, from a costly iterative process to a final verification and validation step. The variability in components material properties and environmental conditions together with the lack of knowledge about the underlying physics of complex systems often make it impractical to make reliable predictions based on only deterministic CAE models.
