(2009-05-15)A finite element model based on the layer-wise theory and the von Kármán type nonlinear strains is used to analyze damage in laminated composite beams. In the formulation, the Heaviside step function is employed to express ...
-
(Texas A&M University, 2007-09-17)In polymer matrix composites (PMCs) manufacturing processes can induce de- fects, e.g., voids, fiber misalignment, irregular fiber distribution in the cross-section and broken fibers. The effects of such defects can be ...
-
(2015-04-29)Due to their low density and high specific strength, magnesium and its alloys are structural metals attractive for the aerospace and automotive industries. However, wide spread use of wrought magnesium is challenged by its ...
-
(2015-08-28)In order to obtain a better understanding the complex mechanical behavior of asphalt binder, its microstructure must be examined. In addition, the interrelationship between asphalt binder microstructure, damage, and ...
-
(2022-05-18)The remaining fatigue-life of existing steel bridge structures is an unresolved thorny issue. Current code-based fatigue rules for new structure design were established on conservative principles that are intended to deliver ...
-
(2009-05-15)The hot-workability of Titanium (Ti) alloys is of current interest to the aerospace industry due to its widespread application in the design of strong and light-weight aircraft structural components and engine parts. ...
-
(Texas A&M University, 2005-08-29)Hot mix asphalt (HMA) is a granular composite material stabilized by the presence of asphalt binder. The behavior of HMA is highly influenced by the microstructure distribution in terms of the different particle sizes ...
-
(2013-11-01)A multiscale computational framework for multiphase composites considering damage is developed in this research. In micro-scale, micromechanics based homogenization methods are used to estimate effective elastic moduli ...
-
(2013-11-08)This work examines composite failure at multiple scales. The first scale that is examined is the fiber-matrix scale, where fibers and matrix are discretely modeled. A model is developed at this scale which includes ...
-
(2009-05-15)The problem of damage accumulation in laminated composite materials hasreceived much attention due to their widespread application in the aerospace, automotive,civil, and sports industries. In the aerospace industry, ...
-
(2012-07-16)It is important to assess and communicate the risk to life and downtime associated with earthquake induced damage to structures. Thus, a previously developed four-diagram/four-step approach to assess direct losses associated ...
-
(2019-11-30)In this dissertation, the concept of seismically resilient bridge columns with polyurethane (PU)-enhanced damage-resistant (DR) joints and replaceable energy dissipating (ED) links is proposed. The proposed system introduces ...
-
(2019-11-13)Damage in concrete has been modeled using various approaches such as fracture mechanics, continuum damage mechanics and failure envelope theories. The current research proposes a new approach to model damage in concrete ...
