Behavior and Flexure Analysis of Balsa Wood Core Sandwich Composites: Experimental, Analytical and Finite Element Approaches
… with respect to the span is also investigated. A finite element model is developed to study the flexural and stress analysis. Based on the results, this thesis proposes a desirable analytical approach that correlates theory with experiment as defined below.

Gravity Induced Stresses in a Shrink-Fit Disk.
… of more complex problems, among them being finite difference techniques and finite element approaches.

Constitutive modeling of advanced thermoset composites with application to sheet forming processes
… and rate dependencies and allows solid finite element modeling that tracks material response on the microscopic level, including fiber wrinkling. The second model is a simplified, transversely isotropic elastic-plastic model that can be used together with a finite element model which …

Transient analyses of viscoelastic materials with applications to numerical models
… three parts. In the first part, the time-domain finite element approach used by commercial tools like ABAQUS and ANSYS is reformulated in a general expression of viscoelasticity that does not require a constitutive relation. An alternative interpolation scheme for the relaxation function and the …

Smoothed Particle Hydrodynamic Modeling of Solid State Additively Manufactured Aluminum Alloys
… AFS-D is challenging because traditional finite element approaches fail to accommodate severe deformation. One solution is to use a meshfree framework, such as smoothed particle hydrodynamics (SPH), which better handles large deformation processes. This work aims to create a meshfree …

Influences of surface quality on the rolling contact fatique behaviour of ceramics
… stresses on the rolling tracks were measured. Finite Element Approaches were also employed to describe the contact stress status. Failure modes in relation to surface quality were discussed. The research has provided an understanding of the finishing process, surface quality and rolling contact …
