2. 1. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses

   Author : Per-Johan Gustafsson; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; corners; test-specimens; strength; tension; fracture mechanics; strain localization; size-effect; flexural strength; LEFM; fictitious crack model; Weibull; FEM; pipes; shear strength; concrete; diagonal tension;

   Abstract : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. READ MORE

4. 2. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification

   Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Öyvind Gregersen; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; tensile strength; tearing resistance; folding endurance; fracture toughness; handsheet former; stratify; multilayer; multiply; reinforcement; refining; beating; abaca; glass fibre; polyester; lyocell; softwood; bond strength; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Abstract : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.

5. 3. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

   Author : Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. READ MORE

6. 4. High-strength laminations for glulam

   Author : Carl-Johan Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; machine-stress-grading; glulam; Bending-strength; lumber; tensile strength; finger-joint;

   Abstract : .... READ MORE

7. 5. Strength Criteria on Grouting Agents for Hard Rock- Laboratory studies performed on gelling liquid and cementitious grout

   Author : Magnus Axelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory study; colloidal silica; rheology; shear strength; Grout; erosion; strength; cement; yield stress; silica sol;

   Abstract : Grouting is usually successful in excavations at moderate depths and groundwater inflow. At great depths, in post-grouting or in rock with a large inflow of water, grouting is more problematic due to the forces from groundwater. READ MORE
