Arrowhead’s impact on the human skull , Weapon and trauma in the Bronze Age
Introduction: Weapons and Trauma in the Bronze Age The Bronze Age (approximately 3300–1200 BCE, varying by region) marked a transformative period in human history, characterized by the widespread use of bronze for tools, weapons, and armor. As societies became more complex and conflicts more frequent, warfare and interpersonal violence became prominent aspects of Bronze Age […]
Cyclic Test Analysis of Concrete-Filled Steel Box Column-Validation Model
Introduction Concrete-Filled Steel Box Columns (CFSBCs) are a type of composite structural member that combines the advantages of both steel and concrete. A typical CFSBC consists of a hollow rectangular or square steel section filled with concrete. This hybrid design offers enhanced strength, stiffness, ductility, and energy dissipation capabilities, making it highly suitable for seismic […]
Numerical investigation of concrete-filled double skin steel tubular structure subjected to underwater explosion
Concrete-filled double-skin steel tubular (CFDST) structures are a type of composite structure that consists of two concentric steel tubes (an inner and outer steel tube) with concrete filled in the annular space between them. These structures are increasingly used in offshore, marine, and defense-related applications due to their excellent strength-to-weight ratio, enhanced energy absorption capacity, […]

Crack identification in concrete using piezoelectric materials (PZT) is a non-destructive evaluation (NDE) technique that leverages the unique properties of piezoelectric transducers to detect and monitor structural damage 🔎 Introduction to Crack Identification in Concrete Using PZT Concrete is one of the most widely used construction materials due to its strength and durability. However, over […]
Fire analysis of a timber beam-sequential method
🔥 Introduction to Fire Analysis of Timber Beams Timber is a widely used construction material known for its sustainability, ease of handling, and aesthetic appeal. However, being an organic material, timber is combustible, and its behavior under fire conditions is a critical factor in structural design. Fire analysis of a timber beam involves assessing how […]
Analysis of a reinforced concrete (RC) beam with an embedded spiral GFRP bar subjected to air blast loading
🔷 Introduction Reinforced concrete (RC) structures are widely used in both civilian and military infrastructure due to their strength, durability, and cost-effectiveness. However, under extreme loading conditions such as air blast loads—resulting from accidental or deliberate explosions—conventional RC beams may experience severe damage, including spalling, cracking, or even failure. To improve blast resistance, advanced composite […]
