It's About How and Where We Build: Connecting Energy and Smart Growth [PDF]
, 2006 In recent years, energy issues have become a growing concern for Americans. Largely missing from present energy discussions, however, is the role that land-use practices have on energy consumption and the use of alternative energy resources.

Slip‐resistant connections subjected to freeze‐thaw cycles
Steel Construction, Volume 17, Issue 3, Page 155-163, August 2024.Abstract There are many examples of steel structures subjected to severe environmental conditions with bolted connections directly exposed to climatic agents such as steel bridges, mining transfer towers, wind towers etc. In this experimental research, non‐slip joints with M16 and M20 bolts have been studied. The specimens were subjected to fourteen 12

The Breakdown of Linear Elastic Fracture Mechanics near the Tip of a Rapid Crack
, 2008 We present high resolution measurements of the displacement and strain fields near the tip of a dynamic (Mode I) crack. The experiments are performed on polyacrylamide gels, brittle elastomers whose fracture dynamics mirror those of typical brittle ...

Computing the stress intensity factor range for fatigue crack growth testing at 20 kHz
Engineering Reports, Volume 6, Issue 6, June 2024.A comparative study on the computation of the SIF at 20 kHz load frequency. Results from different simulation procedures are presented and discussed. Abstract Inertia and damping influence the values of the stress intensity factors (SIFs) at high‐frequency loading and they must be included in computations.

Object Grating Method Application in Strain Determination on CTOD Tests
Strain, 2006 Abstract: Standard fracture toughness tests require standard specimens with the presumption that mechanical properties are uniform in the crack growth direction. Standards for crack tip opening displacement (CTOD) fracture tests prescribe remote crack mouth opening displacement, which can lead to inadequate results in the case of heterogeneous ...
