1. 1. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Axel Hallén; Jacob Hjorth; [2022]
   Nyckelord :Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

   Sammanfattning : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. LÄS MER

3. 2. Numerical simulations of shear reinforced concrete beams subjected to blast loads

   Master-uppsats, KTH/Betongbyggnad

   Författare :Anton Frank; Andreas Fristedt; [2021]
   Nyckelord :Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

   Sammanfattning : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.
