41. Computational modeling of hot rolling
Sammanfattning : This thesis consists of six papers on finite element simulations of the hot rolling of plates. Different friction and material models have been evaluated. The work includes both numerical simulation and experimental verification. LÄS MER
42. Ultimate and Residual Strength Assessment of Ship Structures
Sammanfattning : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. LÄS MER
43. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales
Sammanfattning : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. LÄS MER
44. Modeling of material behavior in metal forming
Sammanfattning : With an increasing demand to improve efficiency and to cut costs, the industry is constantly seeking to reduce the time and money spent in product development and manufacturing. Use of computer-based simulations has become more or less a standard tool to meet this demand. LÄS MER
45. Numerical simulations of wear
Sammanfattning : The objective of this licentiate thesis was to study the effect of tool wear for sheet metal forming tools and how the wear process can be simulated in an efficient manner. Three Papers are appended to this licentiate thesis. Paper A covers the influence of tool geometry in deep drawing. LÄS MER
