1. Anisotropic Mechanical Behaviours and Thin-wall Effects of Additively Manufactured Austenitic Alloys
Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a general concept of building a three-dimensional object layer-by-layer. AM breaks through the manufacturing limitations in conventionally subtractive manufacturing, leading to a great design freedom of components with complex geometries. LÄS MER
2. Structural Behavior of Reinforced High-Strength Concrete Columns
Sammanfattning : The high compressive strength of high-strength concrete is especially advantageous in compressed members such as columns, which can be made more slender and, consequently, make economic benefits possible. However, the behavior of high-strength concrete columns is not yet fully understood. LÄS MER
3. Development of a new generation of creep resistant 12% chromium steels: Microstructure of Z-phase strengthened steels
Sammanfattning : Fossil-fuel fired steam power plants provide more than 60% of the electricity generated worldwide, and account for about one third of the global CO2 emissions. Increasing the steam temperature and pressure leads to a higher thermal efficiency of the power plants and thus lower emissions. LÄS MER
4. Nonlinear Creep Model of Paper and Corrugated Board Materials
Sammanfattning : Models of the nonlinear creep behavior of paper, and of the global buckling , local buckling and creep buckling of corrugated board have been developed. The studies of creep and buckling were limited to climate conditions with constant relative humidity. First the short-term elastic buckling of corrugated board panels was studied. LÄS MER
5. Quasi-instantaneous and Long-term Deformations of High-Performance Concrete with Some Related Properties
Sammanfattning : This report outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High-Performance Concrete, HPC, with some related properties. For this purpose about two hundred small cylinders and about one thousand cubes of eight types of HPC were cast. The age at loading varied between 18h and 28 days. LÄS MER
