Study on coalescence criterion of double elliptic cracks in finite homogeneous plates under the uniaxial tensile load based on GTN model

Jixie qiangdu
Based on the Gurson-Tvergaard-Needleman (GTN) damage model, the coalescence behavior of double elliptical cracks with different sizes and the coalescence criterion based on crack spacing ratio was studied in homogeneous plates with elliptical double ...

Influence of Stirrup-Tie Shape on Inelastic Cyclic Response of Flanged Reinforced Concrete Flexural Members [PDF]

, 1981
Three reinforced concrete flanged sections (T-sections) having different shapes of shear reinforcement were subjected to cyclic inelastic flexure representative of what framed structure members might-be forced to endure during a severe earthquake. The

Investigation of Stress Intensity Factors in Welds of Steel Girders Within Steel–Concrete Composite Structures

Buildings
Fatigue damage in steel–concrete composite structures frequently initiates at welded joints due to stress concentrations and inherent defects. This study investigates the stress intensity factors (SIFs) associated with fatigue cracks in the welds of ...

Within Breathing Space or Through a Cracked Divider?

PARSE Journal
Based on two collective art activities at “The Lost-and-Found” academic symposia held at the National Museum in Warsaw and on the Riga to Dubulti train in 2024, this paper reflects on art-based research. I propose that art research can serve as an effective method to revitalize the teaching of art history, as it embraces a multiplicity of ...
