We had the honor to be selected as the computer simulation partner for a recent Auto/Steel Partnership (A/SP) study that considered the feasibility of using higher strength and advanced high-strength steels to achieve weight reductions of hemmed closure panels: project…

The Formability of sheet metals Previous posts Materials Matters- “The known unknowns”  and “Material plasticity visualized” covered the general aspects, common terminology, and formulation of the plastic properties in sheet metal forming problems. Accurate definition of flow curves, kinematic hardening…

Springback of sheet metal stamped parts is a challenge faced by tooling suppliers and their customers; parts produced in stamping dies require significant effort in engineering and simulation to arrive at reasonable dimensional accuracy during process design. Conventional methods for…

The Stamping System

A recurring theme on this blog, so far, has been sources of variation in production that might not be apparent to engineers when defining, running, and evaluating a single simulation on any specific product/process design. Comments on the blog and…

Haben Sie bereits einen Presshärteprozess ausgelegt? Wie bestimmen Sie, welche Prozessgestaltung und welche Parameter für die Herstellung von hochqualitativen Presshärteteilen erforderlich sind? Die Finite Elemente Methode ist ein geeignetes Werkzeug, um Parameterwerte auszulegen und deren Einfluss auf die gesamte Prozessgestaltung…

It seems that you cannot have a discussion about High Strength Steel (HSS) and Advanced High Strength Steel (AHSS) without springback shortly becoming the center of attention. Springback in high strength steels is the center of much on-going research. Surprisingly,…

In tryout and production the engineering “boundary conditions” used during simulation are often different than production reality. Physical presses and tools flex, press slides and beds are not perfectly parallel, lubrication is not homogeneous, material properties vary, blank shapes differ,…
