FEA
1. Answer True or False below. (2 points each) When performing a nonlinear FE analysis, pressure is considered a “follower force.” Once an element aspect ratio exceeds 1, the larger the aspect ratio, the better the element performs. Eigenvalue buckling provides a good estimate of the Euler critical buckling load. It is important to include the Bauschinger effect in your FE model when simulating problems that experience large strain. Buckling can be considered as the inverse of stress stiffening....

Ideal Column with Pin Supports Learning Goal: To use the formula for the critical load, i.e., the Euler buckling load, for pin-supported columns to calculate various parameters of columns. Ideally, a column that is perfectly straight and has an axial load applied exactly at the centroid of its cross section will not yield until the internal normal stress reaches the yield stress of the material. Real-world columns, however, are subject to small asymmetries, whether due to irregularities of shape or...

Design the cooling system used to manufacture the leg of a table, shown in Fig.2. You will have to determine the required diameter D so that the leg can withstand 100 kg of axial loading. Once the diameter has been determined, you will need to determine the Revolutions per Minute (RPMs) of the fan needed to cool down the leg to 90-C in less than 2 minutes before it starts deforming after being 3D printed. Consider the leg of the...

A column is made from a rectangular bar whose cross section is 5.5 cm by 9.1 cm . If the height of the column is 2 m, what is the maximum load it can support? The material has E = 200 GPa and Oy = 250 MPa Express your answer with appropriate units to...

Elementary Differential Equation Unit Step Function Problem
Project 2 A Spring-Mass Event Problenm A mass of magnitude m is confined to one-dimensional motion between two springs on a frictionless horizontal surface, as shown in Figure 4.P.3. The mass, which is unattached to either spring, undergoes simple inertial motion whenever the distance from the origin of the center point of the mass, x, satisfies lxl < L. When x 2 L, the mass is in contact with the spring on the...
