  1. 1. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Gabriella Zimmerman; [2023-11-07]
    Keywords : plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Abstract : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. READ MORE

  3. 2. Case study of a 19th century gypsum cast of the Parthenon Frieze

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Lisa Bandgren; [2019-06-19]
    Keywords : Plaster casts; gypsum; Parthenon Frieze; Göteborgs Museum;

    Abstract : This thesis is a case study of a 19th century gypsum cast of block WXI of the Parthenon Frieze. The gypsum cast is part of a continuous collection of eleven gypsum casts of the west part of the Frieze, casts of the blocks WI - WXI. The collection is housed in the Conservation Department at the University of Gothenburg. READ MORE

  4. 3. The influence of microstructural deformations and defects on mechanical properties in cast aluminium components by using Digital Image Correlation Techniques (DICT)

    University essay from Högskolan i Jönköping/Tekniska Högskolan

    Author : Jahanmehr Armanjo; [2015]
    Keywords : Al-Si cast alloys; AlSi7Mg0.3; strontium modification; heat treatment; SDAS Secondary Dendrite Arm Space ; Aramis; digital image correlation technique DICT ; mechanical properties ultimate tensile strength; offset yield strength and elongation ; plaster mould processes;

    Abstract : Digital image correlation techniques (DICT), a non-contact deformation measuring technique based on gray value digital images, have become increasingly used over the last years. By using the DIC technique during a tensile test, the deformation behavior of different engineering material under an applied load can be determined and analyzed. READ MORE

  5. 4. TAILORING PROPERTIES TO REPRESENT HPDC TENSILE AND FATIGUE BEHAVIOUR IN ALUMINIUM-SILICON CAST ALLOY PROTOTYPES

    University essay from Högskolan i Jönköping/JTH. Forskningsmiljö Material och tillverkning – Gjutning

    Author : Martin Ignacio Riestra Perna; [2015]
    Keywords : Aluminium alloys; Prototyping solutions; Sand cast; Plaster cast; Tensile properties; Fatigue properties;

    Abstract : The work presented aims to find alternatives for the prototyping of components by sand and plaster mold manufacturing processes that deliver properties similar to high pressure die casting (HPDC). Sand and plaster test samples have been casted. The Al-7Si-0. READ MORE

  6. 5. The Harpy Tomb: An Experimental Visibility Analysis

    University essay from Lunds universitet/Antikens kultur och samhällsliv

    Author : Peter Fange; [2014]
    Keywords : The Harpy Tomb; 3D models; Xanthus; Lycia; digital acquisition; visibility; digital reconstruction; Blender; Meshlab.; History and Archaeology;

    Abstract : A study done on the Harpy Tomb at Xanthus in ancient Lycia. This study is an experimental visibility analysis, the purpose of which is to explore to what extent the geometry of the bas-relief panels would be visible. Aspects which are taken into consideration for this purpose include distance and varying positions, as well as time of day. READ MORE
