Quantifying Damage Evolution in Fiber-reinforced Composites Using Fracture Mechanics
Abstract: By evaluating the evolution of damage, such as cracks or delamination, within the material over time or under various loading situations, damage evolution in fiber-reinforced composites can be characterized using fracture mechanics. Fracture mechanics offers a framework for understanding and projecting the behavior of materials that already have damage or flaws. Since they have a high strength-to-weight ratio and unique mechanical qualities, fiber-reinforced composites are essential in many branches of …

Damage Evolution and Delamination Resistance in Polymer Matrix Functionally Graded Laminates
Abstract: Functionally graded laminates (FGLs) in polymer-matrix systems represent a promising pathway to enhance damage tolerance and delay delamination in advanced structural composites. In this study, we explore the mechanisms of damage initiation, propagation, and delamination resistance in polymer matrix functionally graded laminates (PM-FGLs) through a combined experimental–computational approach. Laminates with linear, exponential, and bio-inspired gradation profiles were fabricated using vacuum-assisted resin transfer molding (VARTM) and additive manufacturing techniques.

Correlating the Damage Behaviour of Polymer Composites with the Potential Energy of the Impactor
Abstract: Design of structures using composites requires comprehensive evaluation and characterization of mechanical properties in both undamaged and damaged state. Composite laminates undergo combinations of mechanical loading resulting into microdamage accumulation in the plies. The first mode of damage is usually intralaminar cracking with the crack plane transverse to the middle plane of the laminate, spanning the whole width of the laminate. The density of cracks in a ply depends on …

Sedimentation Yield Analysis of Hatnur Dam using SWAT and GIS
Abstract: Sedimentation in reservoirs throughout the world are leading to loss of reservoir storage capacitythereby reduces the useful lifetime of dams. Storage reservoirs built across rivers or streams tend tolose their water storage capacity progressively with the passage of time due to sedimentation. After thedesigned sediment deposition capacity of the reservoir, further addition in sediment deposits affectsthe reservoir regulation operations. It’s therefore necessary to assess reservoir sediment depositioncapacity and plan for …

Robust Design of Damping Controller for Power System using a combination of Flower Optimization algorithm and Optimal Control Theory
Abstract: The power system experience low frequency oscillations due to various disturbances. It is verynecessary to damp these oscillations else it will endanger the system security and stability. High gainand fast acting excitation systems do not provide the necessary damping torque and it can provide thesufficient synchronising torque only. Lack of damping torque causes the oscillations of generator rotor,So, Power system stabilizer (PSS) is used in the proposed work along with …
