Adaptive Structures: Infinitely Stiff, Extremely Slender, Ultra-Light Weight

Designing structures with minimal environmental impact is now a serious concern in the construction sector. Active control has been used in civil engineering structures for a variety of purposes. The most widespread application so far
has been in vibration control. The...Read more

Yield-line pattern
Thursday, June 16, 2016 - 17:15 to 18:15

An evening meeting on the automated yield-line method for concrete slabs is being organised jointly by DSBY (the Danish Society for Structural Science and Engineering, one of the oldest societies of its kind in the world) and IABSE Denmark. The meeting will be held at the Technical University of Denmark...Read more

Thursday, February 26, 2015 - 14:00 to 17:00

This free to attend afternoon workshop is designed to communicate to engineers a recent breakthrough in concrete slab analysis: following research in the CMD research group, the well known 'yield-line' method for concrete slabs has finally been systematically automated.

Benefits of the yield-line method are that it will often identify...Read more

Both presentations are also to be presented at 6th International Conference on Protection of Structures Against Hazards.

Presentation 1: Validation of semi-empirical blast pressure predictions for far-field explosions - is there inherent variability in blast wave parameters?

S. E. Rigby

A considerable amount of scientific effort has been expended over...Read more

Research Seminar: 10th September

Presentation 1: Approximations of the macroscopic strength criterion of reinforced soils, with application to structural stability analyses - Maxime Gueguin

Despite the increasingly widespread use of various soil reinforcement techniques aimed at im-proving the bearing capacity performance of geotechnical structure, devising efficient, rational and reliable engineering design procedures still remains a challenging issue.

An investigation on the use of a reformulated Theory of Critical Distances (TCD) to predict the fracture of notched 6063-T5 aluminium alloy subjected to high rate of loading at room temperature. This theory has been used to predict static and fatigue problems successfully by assuming the linear-elastic behaviour in the...Read more

Damage Modelling in Composite Laminates

The modelling of damage and failure on composites is still an unresolved problem in many aspects. Amongst others:
1). - The existing numerical techniques or methods often diverge before the virtual failure of the material.
2). - There are different concepts about how...Read more

Physical modelling can be used to understand complex soil-structure interactions, which might be difficult to model numerically.  Modern instrumentation (e.g. LVDTs, strain gauges, load cells) allows accurate information to be gathered on the displacement of structural elements. Additionally, modern digital image correlations (DIC) techniques allow displacements within the soil mass...Read more

Microlattices are known to have improved mechanical properties compared to their equivalent solid parts and have sparked many interests in the research communities. For the modelling of such materials with lattice microstructures, various techniques can be used. An emergent theory, the gradient elasticity continuum, can be applied to this microstructure...Read more

Mechanics of Interfaces and Evolving Discontinuities 

Two main approaches can be distinguished for resolving interfaces and evolving discontinuities. Within the class of discrete models, cohesive-surface approaches are probably the most versatile, in particular for heterogeneous materials. However, limitations exist, in particular related to stress triaxiality, which cannot be captured well...Read more
