It has been widely believed that components produced by fused filament fabrication (FFF)
experience weak mechanical properties due to weld lines. However, recent studies …

The crack propagation rate of environmental stress cracking was studied on high-density
polyethylene compact tension specimens under static loading. Selected environmental …

Polyethylene pressure pipes are designed for service lives of at least 50 years. While so far
lifetimes have been assessed by pipe pressure tests, due to improved slow crack growth …

The presence of microplastics in environmental compartments is generally recognized as a
(potential) health risk. Many papers have been published on the abundance of microplastics …

The oxidation behavior and mechanism near the crack of bloom was investigated by
prefabricated crack and oxidation at high temperature (1000–1200° C). The interface oxide …

Two different modes of fracture propagation can occur when a crack encounters a weak
interface in a fused filament fabricated (FFF) part: the crack either deflects into the interface …

Regarding the urgent need for a proper pre-crack generation method in polymeric materials,
this study addressed the design and fabrication of a broaching machining apparatus. The …

One of the preconditions to accurately evaluate materials' fracture behavior is the potential of
generating an appropriate pre-crack in them because the method employed for pre-crack …

The accurate measurement of fracture toughness depends on the accurate determination of
crack initiation. Our previous study demonstrates a relationship between the acoustic …

The effects of soft, polymeric interlayers on a brittle, mineral reinforced polymer matrix are
investigated. Interlayers made of a standard polypropylene (PP) and a soft type of PP are …
