  1. 1. Cohesive modelling of the temperature dependence of epoxy based adhesives in Mode I and Mode II loading

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Tomas Walander; Högskolan i Skövde.; Högskolan i Skövde.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology; Cohesive laws; Epoxy adhesive; Fracture energy; Peak stress; Temperature; Regression analyses; Shear modulus; Young’s modulus.;

    Abstract : In this work, the influence of the temperature on the cohesive laws for two epoxy adhesives is studied at temperatures below the glass transition temperature for both Mode I and Mode II loading. Cohesive laws are measured experimentally under quasi-static loading conditions in the temperature range -30≤T≤80"C" . READ MORE

    University dissertation from Mats Svensson, Geotechnology, Box 118, 221 00 LUND

    Author : Mats Svensson; Lund University.; Lunds universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; Spectral Analysis of Surface Waves; shear modulus; SASW; multichannel; inversion; Gmax; teknisk geografi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; geographical and geological engineering; Hydrogeology; Civil engineering; hydraulic engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : With the main aim to test the applicability of the surface wave seismic technique Spectral Analysis of Surface Waves (SASW), used for determination of the shear stiffness (shear modulus - Gmax), four areas of applications have been studied. The four areas have been sites with natural geological conditions, sites where non destructive testing is necessary, pavement testing and multichannel testing. READ MORE

  3. 3. Energy Absorbing Material Concepts for Automotive Accident Injury Prevention

    University dissertation from Stockholm : Farkost och flyg

    Author : Rickard Juntikka; KTH.; [2004]
    Keywords : Head impact; energy absorption; cellular materials; automotive; dynamic; pedestrian; interior; compression; shear; finite element analysis; optimisation;

    Abstract : Although automotive safety has experienced a rapiddevelopment during the last decades, traffic related accidentsrank very high in many countries in terms of cause of death.Statistics show that the head is the body region mostfrequently injured in motor vehicle accidents and the primarycause of death is head injuries.

    Abstract : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. READ MORE

  5. 5. Investigations of thermophysical properties of slags with focus on slag-metal interface

    University dissertation from Stockholm : KTH

    Author : Luckman Muhmood; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering Metallurgical process engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik Metallurgisk processteknik;

    Abstract : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. READ MORE
