Material Library

FormingSuite provides you with a customizable materials database. Several industry standard materials are included with FormingSuite but with the customizable materials database you have the flexibility to add any material. To open the material database select Material Library from the Tools menu.

To expand the Materials DB dialog box select the Expand button in the lower right corner of the Materials DB dialog box. 

The expanded Material DB dialog box will allow you to add additional material properties, material costing information as well as load user defined Stress Strain curves and user defined Forming Limit curves.

Creating a Custom Material

A custom material can be defined in FormingSuite either by creating a new material or by modifying an existing material.

New material: Click the New button then enter the desired data. The mandatory fields are Name, Thickness, n, r and K or UTS the remaining data fields are optional or have default values. Finally click the Save button to save the new material.
 

Modify an existing material: Select one of the predefined material files then modify the name and/or desired data and finally click the Save button.

Material Property Values

Name - name of the material.

Thickness - is the measured thickness of the model.

n - the work hardening exponent determines the rate at which a material hardens and describes the ability of the material to stretch.

r - the coefficient of anisotropy or r-bar is used to measure the differences in material properties through the thickness of the sheet versus in the plane of the sheet and describes the drawability of a material.

K - the material strength or stress coefficient is used in the power law relationship to determine the shape of the plastic portion of the stress/strain curve.

UTS - the maximum stress that a material can withstand without fracture.

Uniform Elongation - the larger the n value, the greater the material will endure uniform elongation before necking occurs.

Yield Stress - the stress at which plastic (permanent) deformation begins and elastic deformation stops.

FLD0 - the point where the forming limit curve intersects the major strain axis of the forming limit diagram. Determines how soon a material will split. A zero value for FLD0 will result in a calculated based on material thickness, yield strength and n-value.

E - Young's Modulus, the coefficient of elastic stretching is the ratio of the linear stress to the linear strain.

Poisson's Ratio - the ratio of the stretch perpendicular to and in-line with the stress.

Thinning Limit - is the amount of force that can be applied before the material wrinkles or breaks. Default value is 0.25%.

Shear Limit - is the amount of force that can be applied before the material is sheared or twisted. Default value is 0.65.

Density - is the amount of mass contained per unit volume.

Friction - The resistance to relative motion between two surfaces in contact. Default value is 0.15.

Material Cost Values

Base Cost - the base cost of the material.

Scrap Value - the value of the cost of the scrap material.

Extra Material Cost - any other material cost.

Consumables - is any additional cost that cannot be measured in $/kg. i.e., electricity, labor, etc.
