Most of the out-of-plane experimental studies of steel plate composite (SC) walls have used tie bars instead of tie plates. It has been postulated that tie plates with high aspect ratios (i.e., tie plates with wide widths) may lower the out-of-plane shear capacity of the...
K&C is pleased to present Principal Scientist, Dr. H. Luo's publication titled: "Mapping the Young's modulus distribution of the human tympanic membrane by microindentation" . This peer-reviewed research paper provides quantitative results to characterize the mechanical properties of the eardrum (the tympanic membrane). The eardrum is a...
A description and results from validation studies for the Karagozian & Case (K&C) concrete (KCC) model are presented in this paper. This material model is primarily intended for modeling the dynamic responses of RC structural components. It is based on a partially associative plasticity theory...
Composite materials can provide a wide range of capabilities for managing acoustic waves. Through topology optimization K&C designs multilayered composites with optimal structural and acoustic performance. In this paper, a series of ultrasound tests have been done on a multilayered composite and it is observed...
Modeling Concrete Structures with the Finite Element Method There are many problems where conventional blast analysis and design tools are too conservative, which can lead to costly construction costs, or worse, will push the designer to design for failure modes that simply will not happen. K&C has...
Cold-formed steel (CFS) trusses can be an economical framing option for many buildings, and are often the most economical option for those having a steeply sloped roof. Some advantages of CFS trusses are that they have an excellent span-to-weight ratio, can be shop-fabricated into custom...
Dust explosions are a complex phenomenon that can occur when solid dust particles are dispersed as a cloud. In such configurations, solid particles can burn rapidly as the surrounding air acts as an oxidizer and sustains the combustion of the suspended particles once the reaction...
