Fatigue Testing and Analysis of Polymer and Composite Materials Used in Heavy-Duty Trucks

Creator:: Gahan, Kevan
Abstract:: As structural durability analysis is increasingly trusted during the design processes of the automotive industry, more complete and sophisticated modeling of material behavior under both static and dynamic loading conditions is paramount. This is especially true regarding the application of heavy-duty trucks, where modern designs contain large parts such as...

Investigation into the role of strength and toughness in composite materials with an angled incident crack

Creator:: Grimm, Brian A.
Abstract:: Understanding the mechanical behavior of composite materials requires extensive knowledge of fracture behavior as a crack approaches an interface between the bulk material and the reinforcement structure. Overall material toughness can be greatly influenced by the propensity of an impinging crack to propagate directly through the substrate or deflect along...

Experimental characterization of saw chain cutting performance

Creator:: Otto, Andrew W.
Abstract:: Chainsaw users value cutting performance and safety. Knowledge of the forces exerted during sawing are necessary to understand and improve the cutting performance of saw chain. Additionally, cutting forces can be used to form metrics for evaluating performance tradeoffs when using a safety (i.e. low-kickback) saw chain versus a standard...

Experimental Classification of Intralaminar Matrix Compression Damage Propagation in Carbon Fiber Reinforced Polymers

Creator:: Daniels, Mitchell Alan
Abstract:: Composites often are able to carry more load after damage due to the structure of laminates. In addition, damage can be difficult to detect in composites compared to homogeneous materials. Understanding the behavior of composite material after damage is vital for composite structural design. Currently, experimental methods exist for classifying...

Sensitivity of Hashin damage parameters for notched composite panels in tension and out-of-plane bending

Creator:: Wright, Thomas J.
Abstract:: When using Finite Element Analysis (FEA) to model notched composite panels, the values of certain material properties can have a great effect on the outcome of the simulation. Progressive damage modeling is used to model how a composite structure will fail, and how that failure will affect the response of...

Adhesive Properties Subject to Variation in Temperature, Thickness, and Working Time

Creator:: Aerne, Nicholas, S. J.
Abstract:: Adhesive use is becoming increasingly common in manufacturing processes. The advantage of adhesives are light weight components, non-destructive fastening techniques and distribution of loads over the applied bond region. Modeling the behavior of adhesive bond lines in fastening joints can help in the design process to make an optimized joint,...

An investigation of transition from penetration to deflection in the fracture of bi-material interfaces

Creator:: Strom, Joshua L.
Abstract:: The problem of determining whether a crack impinging on an interface will penetrate into the substrate or deflect along the interface is vital to the effective design of layered and composite material systems. Of particular interest is the transition between crack propagation by penetration through an interface and deflection along...

Evaluation of Abaqus for simulating quasi-static Mode III shear of edge notched carbon fiber reinforced polymer panels

Creator:: Hyder, Imran
Abstract:: The ability to engineer stiffness and strength in any desired direction make composites an ideal material candidate for various applications when compared to their traditional isotropic counterparts. In spite of this, the ability to model the material response in composites has yet to be fully explored. Composite research largely focuses...

The dynamic shear moduli of blubber for selected large whale species

Creator:: Summers, Michael P.
Abstract:: Whale blubber is the insular tissue layer located between the dermis and the superficial fascia layer which sheathes the whale's musculature. It is made up of a lipid matrix ramified with strong, structural collagen and elastic fiber bundles, but little is known of its mechanical properties. Knowing these properties adds...

A Novel Progressive Damage and Failure Analysis Model for Matrix Compression using 3D Continuum Damage Mechanics and Smoothed Particle Hydrodynamics

Creator:: Solanki, Satish
Abstract:: The matrix compression behavior is assumed similar to tension, and many material's elastic and damage parameters are considered equal in tension and compression but experimentally not explored. This assumption leads to unrealistic or very far from the actual behavior of the matrix under compression. Moreover, the pre-existing implemented Abaqus models...
