Variable Analysis

An analysis is presented for a semi-infinite strip reinforced by flanges and subjected to concentrated in-plane loads at the ends of the flanges. The taper which results in constant flange stress is determined, and the stress distribution in the sheet is also found. A simple complex variable analysis is used which leads to exact solutions in closed form.

Extremal Character

One of the possible approaches to the analysis of a physical mechanism of time dependence for the resistance coefficients of materials is suggested. The material durability at the constant stress is described using the Zhurkov and Gul' equations and the durability at the alternating stress—using the Bailey criterion. The low strains lead to structuring of a material that is reflected in a reduction of the structure-sensitive coefficient in these equations. This affords 20% increase in the durability. The dependence of the resistance coefficient assumes an extremal character; the maximum is observed at the time to rupture lg tr ≈ 2 (s).

Client Needs

Susan Carter has not been feeling well for days. She would like to see a doctor about her chest pain and wheezing, but Susan knows that missing work will leave her client without a replacement and, worse, she could be fired. Susan is a home healthcare worker in Illinois. Like many of her fellow workers, Susan has no health insurance and cannot afford to risk losing her job by going to see a doctor.Often, Susan feels unable to handle the constant stress of her job. She helps her clients bathe and dress, prepares their meals and assists them with their medications and housekeeping. Susan travels by bus daily to care for two to five clients. She carries a pager day and night in case a client needs help with a plugged catheter or another emergency. Susan often has to work seven days a week, and she steps in to care for patients whose caregivers have left for better-paying jobs.

Half Strip

We construct exact solutions of two inhomogeneous boundary value problems in the theory of elasticity for a half-strip with free long sides in the form of series in Papkovich–Fadle eigenfunctions: (a) the half-strip end is free and (b) the half-strip end is firmly clamped. Initially, we construct a solution of the inhomogeneous problem for an infinite strip. Subsequently, the corresponding solutions for a half-strip are added to this solution, whereby the boundary conditions at the end are satisfied. The Papkovich orthogonality relation is used to solve the inhomogeneous problem in a strip.
