Vibration and wave propagation in ribbed plates
The Journal of the Acoustical Society of America, 1971A formalism for handling problems of wave propagation and forced vibration in ribbed plates is presented. A general solution is obtained for the forced vibration of an infinite thin plate, periodically stiffened by identical, uniform ribs. The ribs are idealized as parallel line attachments capable of exerting line forces and line moments upon the ...

Lightweight Stiffening Ribs in Structural Plates
SAE International Journal of Commercial Vehicles, 2017<div class="section abstract"><div class="htmlview paragraph">The aim of this analysis was to model the effect of adding stiffening ribs in structural aluminum components by friction stir processing (FSP) Nano material into the aluminum matrix. These stiffening ribs could dampen, redirect, or otherwise alter the transmission of energy waves

Design of plates with wide ribs
International Applied Mechanics, 1995The design of plates with wide ribs is an important problem in modern engineering (in the construction of foundations, etc.). It is currently examined from one of two viewpoints. On the one hand, an exact solution can be obtained with hinged support of the plate on the sides perpendicular to the ribs.

Optimal Arrangement of Ribs in Rib-Reinforced Plates and Shells
1994Rib reinforcement of plates and shells is commonly used in machinery, in building structures and in other branches of technology. A problem of an optimal arrangement of ribs in thin rigid-plastic plates with hinged edges was studied in the paper1 in such a formulation: a volume V of material in an initially non-reinforced structure of constant ...

Absorbable Plates for Rib Fracture Repair: Preliminary Experience
The Journal of Trauma: Injury, Infection, and Critical Care, 2003Absorbable prostheses are currently used in a variety of bone reconstructions and fixations.This is a case series of rib fracture fixation using absorbable plates and screws consisting of 70:30 poly(L-lactide-co-D,L-lactide) from April 2001 through November 2002.Ten patients underwent rib fracture fixation with absorbable plates and screws.

Non-diffuseness of vibration fields in ribbed plates
The Journal of the Acoustical Society of America, 2011This paper presents numerical simulations of structural intensity in a rib-reinforced plate, investigating the diffuseness. Many prediction models of building and structural acoustics, such as statistical energy analysis or energy flow methods, assume the vibrational wave fields to be diffuse.

Rib stiffened sound wave projector plate
The Journal of the Acoustical Society of America, 1996A rib-stiffened sound wave projector plate is disclosed which generates lowrequency sound waves in a fluid medium when energized and flexed. A flexible sound wave projector plate includes at least first and second parallel, major planar surfaces. The first major planar surface includes at least one set of sound wave projector plate ribs, disposed ...

Annals of Plastic Surgery, 2013
During microvascular breast reconstruction, exposure of internal mammary vessels (IMVs) is facilitated by the removal of a portion of the rib resulting in occasional chest contour deformity (CCD). The use of rib plating may reduce CCD and reduce postoperative pain.All patients underwent microvascular breast reconstruction using IMVs.

Isothermal extrusion of ribs on plate
Blanking productions in mechanical engineering (press forging, foundry and other productions), 2020Technological schemes and relationships are given for calculating of operating modes during isothermal heating of workpieces. The conditions of viscoplastic non-stationary deformation are accepted. The energy form equilibrium equation as applied to the discontinuous displacement velocity fi eld and material damage kinetics equations are used.

Bounds for frequencies of rib reinforced plates
Journal of Sound and Vibration, 1980Abstract Rigorous upper and lower bounds are presented for the frequencies of vibration of a thin elastic plate reinforced by an elastically attached rib. This study has two purposes: the first is to indicate how a method for lower bounds can be applied to simple built-up structures and the second is to demonstrate the effectiveness of the method in ...
