A Multiaxial Plasticity Model with Softening for Simulating Inelastic Cyclic Local Buckling in Steel Beam Columns Using Fiber Elements

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Diego Isidoro Heredia Rosa

This paper proposes a new effective multiaxial plasticity model to simulate inelastic cyclic buckling in steel frame members. The proposed constitutive formulation is expressed within the framework of rate-independent metal plasticity and replicates the pr ...

How Stress Biaxiality Controls Crack Morphology and Apparent Fracture Energy of Dikes and Sills

Marie Estelle Solange Violay, Antoine Guggisberg

The emplacement of dikes and sills plays a crucial role in crustal mechanics. The parameter used to describe their resistance to propagation, fracture energy, remains controversial. Here, we show how different stress biaxiality levels experienced by dikes ...

Experimental investigation of two-dimensional Mode-II delamination in composite laminates

Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang

The two-dimensional (2D) delamination growth in composite laminates under the Mode-II fracture condition was experimentally investigated using a novel set-up. Circular plate specimens with a centrally embedded pre-crack of two sizes were semi-clamped along ...

Stress fields for the interaction of in-plane and out-of-plane forces in reinforced concrete shell elements

Marie-Rose Backes

Plane reinforced concrete (RC) elements are used in a large variety of structures. Their principal function is to carry forces that act in the plane of the element, but external actions and connections to other structural elements generally introduce addit ...

Exploring the potential of the critical shear crack theory for reinforced and post-tensioned glass beams: Initial analysis and experiments

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state ...
