Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]

open access: yes, 1981
One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

Experimental-numerical validation of the curing reaction of snap-cure polymer systems for component families of small batch sizes and high diversity [PDF]

open access: yesMATEC Web of Conferences, 2021
The efficient production of component families of small batch sizes and high diversity requires numerical analyses of manufacturing processes, especially for complex shaped components made of fibre-reinforced thermosets. In the case of snap-cure systems,

Material modelling and property mapping for structural FEA of thin-walled additively manufactured components

open access: yesVirtual and Physical Prototyping, 2021
Additive manufacturing is progressively paving the way for optimised lightweight components that, due to their typically complex shape, would hardly be feasible with traditional production methods.

The Lightweight Design of a Dump Truck Frame based on Dynamic Responses [PDF]

open access: yes, 2012
This paper develops a new scheme for the lightweight design of heavy dump truck frames based on the characteristics of dynamic responses. The dynamic response is predicted using a finite element (FE) model which is verified by an experimental mode ...

A lightweight universe? [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
How much matter is there in the universe? Does the universe have the critical density needed to stop its expansion, or is the universe underweight and destined to expand forever? We show that several independent measures, especially those utilizing the largest bound systems known—clusters of galaxies—all indicate that the mass-density of the universe ...
