Mechanical properties and structural transitions in the new rigid-rod polymer fibre PIPD (`M5') during the manufacturing process
TL;DR: The polymer poly{2,6-diimidazo[4,5-b:4′,5′-e]pyridinylene-1,4(2,5)-dihydroxy)phenylene} (PIPD) is spin from a liquid crystalline solution in polyphosphoric acid as discussed by the authors.

Nylon-6/rubber blends: 6. Notched tensile impact testing of nylon-6/(ethylene-propylene rubber) blends
TL;DR: In this paper, the deformation and fracture behavior of nylon-6/EPR (ethylene-propylene rubber) blends is studied as a function of strain rate and rubber content.

Temporary toughening of polystyrene through mechanical pre-conditioning
TL;DR: In this paper, the effect of mechanical pre-conditioning on the macroscopic deformation of a brittle polymer, notably polystyrene, is studied, and the effect observed is of a temporary nature, as, due to progressive ageing, the yield stress increases and intrinsic softening is restored on a time-scale of minutes.

Woods and composites cantilever beam: A comprehensive review of experimental and numerical creep methodologies
Abstract: Wood and composites cantilever beam structure has gained attention among researchers in the current years due to its universal structural applications, such as bridges, aeroplane wings, buildings, and transmission towers. However, when the structure is exposed to a constant loading for a very long time, it induces a structural collapse due to creep deformation. Therefore, it is essential to understand and identify the initial creep that can lead to structural collapse. In this study, wood and composite materials exhibit the same structural material morphology which performs as anisotropic material as it majorly contributes to failure. In this study, a state-of-the-art review of creep analysis and engineering design is carried out, with particular emphasis on the creep methodology of a cantilever beam. The existing theories and creep design approaches are grouped into two analysis methods, namely experimental and numerical approaches. To be more specific, the experimental works involved two main methods, namely load-based (conventional) and temperature-based (accelerated) techniques. Selected creep test on cantilever beam structure and coupon scale of wood and composite were highlighted and proposed as the building blocks for a prospective structural creep methodology. These aids build confidence in the underlying methods while guiding future work and areas, especially for long-term service of full-scale structure. At the end, the challenges of creep behaviour description accuracy and improvement on the strength criteria in engineering design were presented.

Tensile strength of highly oriented polyethylene. II. Effect of molecular weight distribution
TL;DR: In this paper, the tensile strength of oriented polyethylene filaments is discussed in relation to molecular weight, and it was found that both the molecular weight and its distribution markedly affected tensile strengths.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
