Abstract:
In the present review article general results concerning problems of contact interaction (contact problems) of pre-stressed bodies with rigid, and elastic punches (facings) are presented. The modern classification of investigations on contact problems for bodies with initial stresses is based on two approaches. The first approach is applicable to bodies with a specific type of elastic potential. The second approach is developed in parallel with the first one. It describes investigations on contact problems for pre-stressed bodies with an arbitrary structure of an elastic potential in a general

A remarkable feature of bone is the ability to alter its properties and geometry in response to changes in the mechanical environment.

Transformation-induced plasticity (TRIP) steels are an example of steels used in the automotive industry, where strain-induced martensitic transformations, associated plasticity and work hardening, enhance both the strength and ductility of the material. This has enhanced both the passenger safety (improved crash-performance) and fuel efficiency as less material is consumed (lighter structure). To gain insights into these strain-induced transformations, it is crucial to understand the impact the applied stress/strain on the martensitic transformation and how the resulting strain fields affect

Abstract:
The intent of the experiments reported here was to measure the axial residual strain at the 6:00 position of a girth-weld in the presence of a crack which had propagated a few millimeters from the inside diameter of the llnepipe. The linepipe, 914 mm diameter and average thickness 16.2 mm had been previously examined at Chalk River and the strains at the 1:30, 6:00 and 10:30 positions had been measured prior to the introduction of the crack. Large changes in the level of axial residual strain and introduction of strong through-wall strain gradients are observed on re- welding 16 mm line pipe w

Abstract:
Pipeline isolation tools from three different manufacturers were evaluated using full-scale testing and numerical modeling to evaluate stresses generated in 24-inch diameter pipe material considering tool-induced loads and internal pressure. Finite Element Analysis (FEA) was conducted to calculate stresses and strains considering different pipe sizes, material grades, and internal pressures. The FEA results were used to generate a user-friendly parametric tool that was validated with measurements made using strain gauges installed on the test spools. The program demonstrated that the isolation

Abstract:
A large body of evidence has accumulated showing that plant strains that are tolerant to a particular oxidant stress have a modicum of cross-tolerance to other oxidant stresses, whether caused by transient heat, drought, cold or oxidizing air pollutants or herbicides. We have studied a multienzyme scavenging system associated with oxidant tolerance at the metabolic and molecular levels in the model systems of pea and Conyza. Data from our experimental systems suggest that both development and subcellular compartmentalization play important roles in stress tolerance. The behavior of the chlorop

Full text
Abstract:
A previous study on hydrogen cracking in the heat affected zone of pipeline girth welds and repairs found that large strains in the HAZ transverse to the weld played a major role in causing cracking. Large transverse strains were believed to arise from bending of the weld due to the thermal contraction of the weld around the pipe circumference. Large root strains were simulated in the laboratory using a bend test which enabled the effect of material composition and strength to be studied. In the bend test, the specimen deflection at the onset of cracking, indicated by a drop in load, was used

Abstract:
Our overall goal is to improve insecticidal nematodes by genetically engineering strains capable of entering an enhanced state of dormancy that provides improved stability. Objectives: 1. Clone and sequence tps-l homologue from Steinernema carpocapsae. (Revised: A failure to isolate the tps gene group from Steinernema precipitated a redirection to identifying other genes involved in insecticidal nematode desiccation process.) 2. Incorporate cloned tps-l gene into S. carpocapsae to obtain overexpression, thereby, enhancing desiccation tolerance. (Revised: Other stress genes in addition to tps-l

Abstract:
Ordinarily, buried pipelines undergo little or no movement in service. In a stable soil environment the longitudinal stress in a pipeline seldom approaches the limiting design value set by applicable codes and regulations. Pipeline serviceability under such conditions is seldom, if ever, threatened by the degree of longitudinal stress. In contrast, localized areas may exist along a pipeline where soils and/or slopes are unstable or where subsidence or differential settlement can occur. In these areas, longitudinal stresses may become severe enough to cause a failure. Over the years various tec
