Mechanical loads

This paper investigates flexural behavior and analytical approach for predicting the load and deflection at critical performance points of reinforced concrete (RC) beams strengthened with prestressed carbon fiber-reinforced polymer (CFRP) sheets. A finite element model is developed to simulate the interaction between the RC beam and the CFRP sheets, capturing key aspects such as failure modes, ultimate load, and mechanical behavior across the three phases of failure.

Considering accurate constitutive models is of the utmost importance when capturing the mechanical response of soft tissue and biomedical materials under physiological loading conditions. This paper investigated the behaviour of porcine myocardium in passive rested hearts. This was done by applying biaxial loads on the myocardium.

This thesis aims to develop finite element models for studying vibration of FGM porous beams in thermal environment under moving loads. Both analytical method and finite element analysis are employed in the thesis. The analytical method is used to derive equations of motion for the beam, and the finite element method is then employed to solve the governing equations and to determine the dynamic characteristics of the beams.

Iron overload in the liver may occur in clinical conditions such as hemo-chromatosis and nonalcoholic steatohepatitis, and may lead to the deterior-ation of the normal liver architecture by mechanisms not well understood. Although a relationship between the expression of ICAM-1, and classical major histocompatibility complex (MHC) class I molecules, and iron over-load has been reported, no relationship has been identified between iron overload and the expression of unconventional MHC class I molecules....

Cells in various anatomical locations are constantly exposed to mechanical forces from shear, tensile and compressional forces. These forces are signifi-cantly exaggerated in a number of pathological conditions arising from various etiologies e.g., hypertension, obstruction and hemodynamic over-load.

Metal cutting puts extreme demands on the tool and tool material through conditions of high forces, high contact pressures, high temperatures, and intense chemical attack by difficult to cut work materials. In addition, the tool geometry and cutting conditions in terms of sharp edges, cyclic engagement and presence of cutting fluid will add to the severity. Most often cutting tools are used close to their ultimate resistance against these loads, especially to the limiting thermal and mechanical stresses. ...
