Maximum Yield Strength

This paper aims to model, simulate and perform the static analysis of a go-kart chassis consisting of circular beams. Modelling, simulations and analysis are performed using modelling software i.e. SolidWorks for Go Kart Challenges 2017 (GKC-17). The maximum stress and displacement is determined by performing static analysis. The result of maximum stress is compared to maximum yield strength of maximum stress whether the maximum stress is exceeding the maximum yield strength or not. It can also show the displacement where it shows the deformation of the chassis part when the load applied to the chassis. Keywords: chassis; Go kart; FEA; SolidWorks

Abstract 55-06 and 70-02 Ductile Dura-Bar are continuously cast ductile irons with about 50 and 75% pearlitic microstructures, respectively. 55-06 has about the same tensile strength as SAE 1045 as-hot-rolled steel. Its maximum yield strength and elongation are equivalent to a eutectoid carbon steel. 70-02 Ductile Dura-Bar has somewhat greater tensile strength up to 3 diameter and considerably higher yield strength up through 10 diameter. The elongation of 70-02 is lower than that of 55-06 because of its reduced ferrite content. This datasheet provides information on composition, microstructure, and hardness. It also includes information on heat treating. Filing Code: CI-62. Producer or source: Federal Bronze Products Inc..

Microstructure changes brought by the addition of La element to AZ91 magnesium alloy are studied, also, the precipitating phases were identified and their influence on the mechanical properties of alloys was investigated. Results show La makes refinement of microstructure of the AZ91 alloy, and decrease the size of Mg17Al12 phase. La element takes a priority to react with Al element over Mg, forming binary phase Al11La3 with high melting point. Certain amount of La increases tensile strength, yield strength and elongation. With more addition, La would combine more Al in matrix and decrease strengthening effect, because Al11La3 phase would become coarsening. The mechanical poroerties tests indicate that AZ91+0.16%La alloy has the best properties. Maximum tensile strength, maximum yield strength and elongation are 245MPa, 178MPa and 14.5% respective, increased by 21%, 19% and 48% respectively. The mechanism of La strenthing mechanical properties is proposed that Al11La3 phase enriched on solid-liquid interface, increased the degree of supercooling, refined the grain size and changed the crystal style.

This paper presents a set of process parameter selection rules to deposit a good metal part. A CO2 laser is used to melt metal powder to achieve layer by layer deposition for fabricating three-dimensional parts. Dimensionless numbers characterizing this powder deposition process are identified using Buckingham’s Π-Theorem. These dimensionless numbers are used to identify a range of values for the process parameters, such as the laser power, spot diameter, speed of the xyz stage and powder flow rate, to achieve good quality layers for different materials. The yield and ultimate strengths are examined for parts fabricated with stainless steel 304 (SS 304) powder under three different processing conditions. These stresses are correlated to the operating conditions and physical dimensions of the deposit through the dimensionless similarity parameters. Experimental data indicate that the yield strength of the part is close to the value of standard sample (250 MPa, same as wrought stainless steel SS304). It is also observed that the direction of maximum yield strength is oriented very close to the dominant direction of material solidification. The ultimate strength is found to be considerably less than the ultimate strength of wrought SS 304 (540 MPa) which may be due to the residual stresses generated in the part.

The aims of the experiment were to evaluate the effect of rock phosphate application and combination betweenphosphate-solubilizing bacteria with farm yard manure on nutrient uptake and yield of soybean. Factorial experiment design with two factors was used in randomized complzte block design with three replications. The first factors was level of rockphosphate i.e. : 0; 30; 60; 90 kg P ha· I, and the second factor was combination of phosphate solubili=ing bacteria andfarm yard manure: without phosphate solubi/i=ing bacteria andfarm yard manure; phosphate solubilbing bacteria (Pseudomonas fluorescens); farm yard manure 10 ton ha"I, and phosphate solubilizing bacteria + farm yard manure. The results indicated that rock phosphate and combination of phosphate solubilizing bacteria andfarm yard manure application increased nutrient (N, p, K) uptake and grain yield of soybean. Optimum dosage of rock phosphate in soil without phosphate-solubilizing bacteria andfarm yard manure (control) was 72.15 kg P hdl which gave maximum yield of soybean was 7.73 g pori. While with phosphate-solubilizing bacteria. farm yard manure and phosphate solubilizing bacteria+farm yard manure obtained optimum dosage of rock phosphate were 62.26, 63.94, and 62. 21 kg P hd1 , respectively, which gave maximum yield of soybean were 8.17, 7.95, and 8.43 g pori, respectively.
