Simulation of peridynamic crack growth under low velocity impact using Kalthoff–Winkler model
Introduction Fracture dynamics under impact loading has long been a central topic in solid mechanics, especially for understanding and predicting crack initiation and propagation in brittle materials. Among benchmark problems for dynamic fracture, the Kalthoff–Winkler experiment is widely recognized for its clear depiction of crack branching and propagation direction under oblique impact conditions. This experimental […]
Air blast analysis of a composite panel made of CFRP facing and PET foam core
Introduction to Air Blast Analysis of CFRP-PET Foam Composite Panels 1. Background and Importance Composite sandwich structures, typically comprising Carbon Fiber Reinforced Polymer (CFRP) face sheets and a lightweight core such as Polyethylene Terephthalate (PET) foam, are widely used in aerospace, automotive, and defense industries due to their high stiffness-to-weight ratio, excellent energy absorption, and […]
Simulation Concrete Cylinder Compression Test
The concrete cylinder compression test is a standard laboratory procedure used to determine the compressive strength of concrete. It involves applying a uniaxial compressive load to a concrete cylinder specimen until failure occurs. This test is fundamental in civil engineering, as compressive strength is one of the most critical properties of concrete, directly influencing structural […]
Simulation the CEL water sloshing in the airy CFRP composite tank
The accurate prediction of fluid-structure interaction (FSI) phenomena, such as liquid sloshing, is crucial in the design and safety analysis of lightweight composite tanks used in aerospace and marine applications. Sloshing refers to the oscillatory motion of a liquid inside a container, often induced by external excitations such as acceleration, vibration, or impact. This motion […]
Low and High velocity impact analysis of a T-shaped steel reinforced concrete column
Steel-reinforced concrete (SRC) columns have been widely used in engineering structures, such as super high-rise buildings, bridges, and railway stations, due to the high bearing capacity and excellent seismic resistance of SRC columns, compared to reinforced concrete (RC) columns. columns. During their service life, these structures may experience various kinds of impact-loading, caused by collision, […]
Analysis of adhesively bonded cross-laminated timber-concrete composite under close blast explosion test
The increasing demand for sustainable and resilient building materials has driven the development of hybrid structural systems that combine the advantages of different materials. One such system is the cross-laminated timber–concrete (CLT–concrete) composite, which leverages the high stiffness and compressive strength of concrete with the lightweight, renewable, and ductile characteristics of cross-laminated timber (CLT). These […]
Analysis of cracked concrete column reinforced with GFRP bar under seimic loading
Reinforced concrete (RC) columns are critical structural components in buildings and infrastructure, particularly in seismic-prone regions where they must resist significant lateral and axial loads. Traditional reinforcement using steel bars offers high strength and ductility, but it is susceptible to corrosion, which compromises long-term durability and performance. As a corrosion-resistant alternative, Glass Fiber Reinforced Polymer […]
Simulation of HJBFRP confined UHPC column under compression Load
The demand for sustainable, high-performance construction materials has driven significant research into the development of eco-friendly composites and advanced concrete technologies. Ultra-high-performance concrete (UHPC) has emerged as a superior material in structural engineering due to its exceptional compressive strength, durability, and ductility. However, like all brittle materials, UHPC can benefit significantly from external confinement to […]
