Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Fracture assessment of post-buckled offshore pipeline using eXtended finite element method

Applied Ocean Research
Shallowly buried offshore pipelines operating under high pressure and high-temperature conditions are susceptible to upheaval buckling. Such pipelines may contain pre-existing defects, including fabrication- or operation-induced cracks.

Experimental Investigation on Crack Growth in Pre-Notched Concrete Beams

Proceedings, 2018
It is well-known that failure of unreinforced, pre-notched concrete beams in bending is mainly governed by the tensile strength (“ductile” behaviour) or by the fracture toughness (brittle behaviour) depending on the geometrical scale (beam size), and the

Validation of a wide plate finite element model using digital image correlation [PDF]

, 2011
To investigate the influence of global plastic deformations on girth weld defect tolerance in pipelines, a parametric finite element model has been developed. This paper provides an experimental validation of the model.
