An Analysis of Dynamic Crack Propagation in A Rail Web with Longitudinal Residual Stressesudinally split rail was developed. This model supplemented finite element fracture mechanics analyses that were unable to effectively address these conditions. The findings of this research specifically indicate that, if the rail does not have adequate dynamic fracture resistance, rail residual stre

Finite- Element-analysis and Algorithms for Large Elastic Strainsn be ensured. Especially Neo-Hooke materials and a constitutive equar tion due to Ciarlet are treated both in material and spatial description..A finite-element-algorithm is developed starting from the Fréchet-derivative of the principle of virtual work in material coordinates. Pushingforward this l

A Linearization Method for Multilevel Optimization solved simultaneously, followed by solution of a large system-level control problem. The sublevel problems involve minimizing a parameter of the designer’s choice over a subset of the design variables, subject to a set of exact and approximate constraints. The system-level optimization consists of

Harbor - A Program for Horizontal Load Analysis of Marine Structures, dockes etc., i.e. structures consisting basically of a slab supported by a substantial number of vertical and raked piles. Equations of equilibrium and motion are formulated and special emhasis is given to the problem of impact of a ship. It is analyzed by direct evaluation of internal impulses an
