Flexural modulus, flexural strength, and stiffness of fiber-reinforced posts.
BACKGROUND The radiopacity degree of posts is not enough for adequate visualization during radiographic analyses. Glass fiber post with stainless steel reinforcement has been fabricated in an attempt to overcome this limitation. AIM This study was designed to determine the influence of this metal reinforcement on the post mechanical properties. MATERIALS AND METHODS This study evaluated fle...
متن کاملThe Genetic Architecture of Maize Stalk Strength
Stalk strength is an important trait in maize (Zea mays L.). Strong stalks reduce lodging and maximize harvestable yield. Studies show rind penetrometer resistance (RPR), or the force required to pierce a stalk rind with a spike, is a valid approximation of strength. We measured RPR across 4,692 recombinant inbreds (RILs) comprising the maize nested association mapping (NAM) panel derived from ...

The correlation between RPR and The rind penetrometer is an effective tool for measuring stalk EH is of interest in terms of direct vs. indirect selection strength in an effort to improve maize (Zea mays L.) germplasm for stalk lodging resistance. However, previous studies have indicated a for stalk strength. That is, to wh...
متن کاملEffects of Reinforcement Geometry on Strength and Stiffness in Adhesively Bonded Steel-Timber Flexural Beams
A finite element model is developed to analyse, as a function of volume fraction, the effects of reinforcement geometry and arrangement within a timber beam. The model is directly validated against experimental equivalents and found to never be mismatched by more than 8% in respect to yield strength predictions. Yield strength increases linearly as a function of increasing reinforcement volume ...

Selection for rind penetrometer resistance (RPR) has proven useful in enhancing germplasm lodging. for stalk strength,...
